    Question:1

    Which of the following statements about the autotrophs is incorrect?
    (a) They synthesise carbohydrates from carbon dioxide and water in the presence of sunlight and chlorophyll
    (b) They store carbohydrates in the form of starch
    (c) They convert carbon dioxide and water into carbohydrates in the absence of sunlight
    (d) They constitute the first tropic level in food chains

    Answer:C

    Autotrophs can convert CO2 and H2O into carbohydrates only in the presence of sunlight. Autotrophs have chlorophyll which takes sunlight and breaks water into hydrogen and oxygen and converts CO2 into carbohydrates but happens only in the presence of sunlight.
    So statement (c) is incorrect and thus it is the right answer.

    Question:2

    In which of the following groups of organisms, food material is broken down outside the body and absorbed?
    (a) Mushroom, green plants, Amoeba
    (b) Yeast, mushroom, bread mould
    (c) Paramecium, Amoeba, Cuscuta
    (d) Cuscuta, lice, tapeworm

    Answer: (b)

    Yeast, mushroom and bread mould are saprophytes. They break down and convert complex organic molecules present in dead and decaying matter into simpler substances outside their body. These simpler substances are then absorbed by them. This is known as saprotrophic nutrition.
    Hence option (b) is correct.

    Question:3

    Select the correct statement
    (a) Heterotrophs do not synthesise their own food
    (b) Heterotrophs utilise solar energy for photosynthesis
    (c) Heterotrophs synthesise their own food
    (d) Heterotrophs are capable of converting carbon dioxide and water into carbohydrates

    Answer:(a)

    Heterotrophs are those organisms which cannot make their own food from inorganic substance like CO2 and water. They depend on autotrophs.
    Hence only statement (a) is correct.

    Question:4

    Which is the correct sequence of parts in human alimentary canal?
    (a) Mouth \rightarrow stomach \rightarrow small intestine \rightarrow oesophagus \rightarrow large intestine
    (b) Mouth \rightarrow oesophagus \rightarrow stomach \rightarrow large intestine \rightarrow small intestine
    (c) Mouth \rightarrow stomach \rightarrow oesophagus \rightarrow small intestine \rightarrow large intestine
    (d) Mouth \rightarrow oesophagus \rightarrow stomach \rightarrow small intestine \rightarrow large intestine

    Answer:(d)

    The food enters trough mouth then passes to the stomach via Oesophagus then to the small intestine and then to the large intestine.
    Hence, the correct sequence of the main parts of the alimentary canal is:
    • The Mouth and Oral cavity.
    • Oesophagus.
    • Stomach.
    • Small intestine.
    • Large intestine.
    Hence option (d) is correct.

    Question:5

    (a) Pepsin
    (b) Mucus
    (c) Salivary amylase
    (d) Bile

    Answer:(b)

    Pepsin is a stomach enzyme that serves to digest proteins found in ingested food.
    Mucus is present in the gastric juice which is secreted by the glands present in the stomach wall. It helps to protect the stomach lining from Hydrochloric acid secreted by it.
    Salivary amylase is an enzyme which breaks down starch present in the food in the mouth.
    Fat breaks down in the small intestine by bile.
    Hence option (b) is correct.

    Question:7

    Which part of alimentary canal receives bile from the liver?
    (a) Stomach
    (b) Small intestine
    (c) Large intestine
    (d) Oesophagus

    Answer: (b)

    Bile is a liquid that is made and delivered by the liver and put away in the gallbladder.
    Small intestine receives bile from the liver, which is normally stored in the gall bladder.
    Bile assists with digestion. It separates fats into unsaturated fats, which can be taken into the body by the stomach.

    Question:8

    A few drops of iodine solution were added to rice water. The solution turned blue-black in colour. This indicates that rice water contains
    (a) complex proteins
    (b) simple proteins
    (c) fats
    (d) starch

    Answer:(d)

    Starch solution on addition of iodine turns blue-black in colour and this test is used as conformation test for iodine.
    The iodine–starch test is a chemical reaction that is used to test for the presence of starch or for iodine. The combination of starch and iodine is intensely blue-black.

    Question:9

    In which part of the alimentary canal food is finally digested?
    (a) Stomach
    (b) Mouth cavity
    (c) Large intestine
    (d) Small intestine

    Answer:(d)

    The food is finally digested in the small intestine due to microvilli which increases the surface area and has a lot of blood vessels which absorbs food and delivers to all the other parts of the body.
    The muscles of the small intestine tract blend food in with stomach related juices from the pancreas, liver, and digestive system, and push the combination forward for additional absorption.
    The walls of the small intestine retain water and the processed supplements into your circulatory system. The waste products of the digestive process move into the large intestine.

    Question:10

    (a) Glucose \overset{cytoplasm}{\rightarrow} Pyruvate \overset{mitochondria}{\rightarrow} Ethanol + Carbon dioxide
    (b) Glucose \overset{cytoplasm}{\rightarrow} Pyruvate \overset{cytoplasm}{\rightarrow} Lactic acid
    (c) Glucose \overset{cytoplasm}{\rightarrow} Pyruvate \overset{mitochondria}{\rightarrow} Lactic acid
    (d) Glucose \overset{cytoplasm}{\rightarrow} Pyruvate \overset{cytoplasm}{\rightarrow} Ethanol + Carbon dioxide

    Answer:(d)

    Anaerobic respiration occurs in the absence of oxygen. It is carried out by yeast and some bacteria.
    Glucose breaks down into pyruvate in absence of oxygen. The reaction is as follows:
    Glucose \overset{cytoplasm}{\rightarrow} Pyruvate \overset{cytoplasm}{\rightarrow} Ethanol + Carbon dioxide
    Glucose breaks down into ethanol, carbon dioxide

    Question:13

    Which of the following is most appropriate for aerobic respiration?
    (a) Glucose \overset{mitochondria}{\rightarrow} Pyruvate \overset{cytoplasm}{\rightarrow} CO_{2} + H_{2}O + Energy

    (c) Glucose \overset{cytoplasm}{\rightarrow} Pyruvate + Energy \overset{mitochondria}{\rightarrow} CO_{2} + H_{2}O
    (d) Glucose \overset{cytoplasm}{\rightarrow} Pyruvate + Energy \overset{mitochondria}{\rightarrow} CO_{2} + H_{2}O + Energy

    Answer: (b)

    Aerobic respiration uses oxygen for respiration. It takes place in the mitochondria. After glycolysis, pyruvate (from the cytoplasm) enters mitochondria and is oxidized in a series of reaction to form CO_{2}, H_{2}Oand ATP. The reaction is as follows:
    Glucose \overset{cytoplasm}{\rightarrow} Pyruvate \overset{mitochondria}{\rightarrow} CO_{2} + H_{2}O + Energy

    Question:14

    Which of the following statement(s) is (are) true about respiration?
    (i) During inhalation, ribs move inward and diaphragm is raised
    (ii) In the alveoli, exchange of gases takes place i.e., oxygen from alveolar air diffuses into blood and carbon dioxide from blood into alveolar air
    (iii) Haemoglobin has greater affinity for carbon dioxide than oxygen
    (iv) Alveoli increase surface area for exchange of gases
    (a) (i) and (iv) (b) (ii) and (iii)
    (c) (i) and (iii) (d) (ii) and (iv)

    Answer:(d)

    During inhalation, diaphragm pulls downward which induces the lower ribs to move upward and forward. Hence the given statement is false. The alveoli are the place where the lungs and the blood trade oxygen and carbon dioxide during the way toward breathing in and breathing out. In the alveoli, exchange of gases takes place i.e., oxygen from alveolar air diffuses into blood and carbon dioxide from blood into alveolar air. This statement is true.
    Oxygen ties to the iron particles in the haemoglobin while carbon dioxide CO_{2} is bound to the haemoglobin chains of the structure. Hence haemoglobin has greater affinity for oxygen than carbon dioxide. Hence the given statement is false. Many alveoli are present in the lungs with a shape that further increases surface area for exchange of gases. This statement is true.
    Hence option (d) is correct.

    Question:15

    Which is the correct sequence of air passage during inhalation?
    (a) Nostrils \rightarrow larynx \rightarrow pharynx \rightarrow trachea \rightarrow lungs
    (b) Nasal passage \rightarrow trachea \rightarrow pharynx \rightarrow larynx \rightarrow alveoli
    (c) larynx \rightarrow nostrils \rightarrow pharynx \rightarrow lungs
    (d) Nostrils \rightarrow pharynx \rightarrow larynx \rightarrow trachea \rightarrow alveoli

    Answer:(d)

    Air is drawn into our body through the nostrils, then it goes into nasal passage from there it enters pharynx then to larynx to trachea to finally alveoli where the final oxygen and carbon dioxide are exchanged.
    So the correct passage is: Nostrils ⇒ pharynx ⇒ larynx ⇒ trachea ⇒ alveoli
    Hence option (d) is correct.

    Question:16

    During respiration exchange of gases take place in
    (a) trachea and larynx
    (b) alveoli of lungs
    (c) alveoli and throat
    (d) throat and larynx

    Answer:(b)

    Alveoli is the place where the exchange of carbon dioxide and oxygen takes place.
    Air is drawn into our body through the nostrils, then it goes into nasal passage. From there it enters pharynx and then to larynx to trachea to finally alveoli where the final oxygen and carbon dioxide are exchanged.
    Hence option (b) is correct.

    Question:17

    Which of the following statement (s) is (are) true about heart?
    (i) Left atrium receives oxygenated blood from different parts of body while right atrium receives deoxygenated blood from lungs
    (ii) Left ventricle pumps oxygenated blood to different body parts while right ventricle pumps deoxygenated blood to lungs
    (iii) Left atrium transfers oxygenated blood to right ventricle which sends it to different body parts
    (iv) Right atrium receives deoxygenated blood from different parts of the body while left ventricle pumps oxygenated blood to different parts of the body
    (a) (i)
    (b) (ii)
    (c) (ii) and (iv)
    (d) (i) and (iii)

    Ans.(c)
    The right atrium receives oxygen-poor blood from the body and pumps it to the right ventricle.
    The right ventricle pumps the oxygen-poor blood to the lungs through the pulmonary valve.
    The left atrium receives oxygen-rich blood from the lungs and pumps it to the left ventricle through the mitral valve.
    The left ventricle pumps the oxygen-rich blood through the aortic valve out to the rest of the body.
    Hence option (c) is correct.

    Question:18

    What prevents back flow of blood inside the heart during contraction?
    (a) Valves in heart
    (b) Thick muscular walls of ventricles
    (c) Thin walls of atria
    (d) All of the above

    Answer:(a)

    Valves ensure there is no backflow of blood inside the heart during contraction they close and separate oxygenated and deoxygenated blood from mixing.
    Thick muscular walls of ventricles have to pump blood out of the heart.
    Thin walls of atria carry the blood towards the heart.
    Hence option (a) is correct.

    Question:19

    Single circulation i.e., blood flows through the heart only once during one cycle of passage through the body, is exhibited by
    (a) Labeo, Chameleon, Salamander
    (b) Hippocampus, Exocoetus, Anabas
    (c) Hyla, Rana, Draco
    (d) Whale, Dolphin, Turtle

    Answer:(b)

    Animal group Heart Examples
    Amphibians and Reptiles 3-chambered heart Salamander, Hyla,
    (two atria and one ventricle) Rana (Amphibians)
    Chameleon,
    Draco, Turtle
    Fishes 2-chambered heart Hippocampus,
    (one atrium and Labeo, Anabas,
    one ventricle) Exocoetus etc.
    Birds and mammals 4-chambered heart Pigeon, parrot,
    (two atria and whale, dolphins,
    two ventricle) humans

    Question:20

    In which of the following vertebrate group/groups, heart does not pump oxygenated blood to different parts of the body?
    (a) Pisces and amphibians
    (b) Amphibians and reptiles
    (c) Amphibians only
    (d) Pisces only

    Answer:(d)

    Fishes have a single closed circulatory system. In this, blood is contained inside blood vessels and circulates in a single direction. Blood flows from the heart around the systemic circulatory route, then returns to the heart again.
    Fishes have two-chambered heart that has only one atrium and one ventricle. The atrium gathers blood that has gotten back from the body and the ventricle pumps the blood to the gills where gas exchange takes place and the blood is re-oxygenated; this is called gill circulation or gill flow.
    The blood at that point proceeds through the remainder of the body prior to showing up back at the atrium; this is called systemic circulation. This unidirectional progression of blood delivers a slope of oxygenated to deoxygenated blood around the fish's fundamental circuit. The outcome is a breaking point on the measure of oxygen that can arrive at some of the organs and tissues of the body, reducing the overall metabolic capacity of fish.
    So the answer is option (d), Pisces only.

    Question:21

    Choose the correct statement that describes arteries.
    (a) They have thick elastic walls, blood flows under high pressure; collect blood from different organs and bring it back to the heart
    (b) They have thin walls with valves inside, blood flows under low pressure and carry blood away from the heart to various organs of the body
    (c) They have thick elastic walls, blood flows under low pressure; carry blood from the heart to various organs of the body
    (d) They have thick elastic walls without valves inside, blood flows under high pressure and carry blood away from the heart to different parts of the body.

    Answer: (d)

    Arteries are the vessels which carry blood away from the heart to various organs of body. As the blood flows away from heart with very high-pressure, arteries have thick walls.
    Hence option (d) is correct.

    Question:22

    The filtration units of kidneys are called
    (a) ureter
    (b) urethra
    (c) neurons
    (d) nephrons

    Answer:.(d)

    Nephrons are the structural unit of kidneys. It is the structural unit of a kidney.
    A nephron is utilized to separate water, particles and little atoms from the blood, filter through wastes and poisons, and return required particles to the blood.
    Hence option (d) is correct.

    Question:23

    Oxygen liberated during photosynthesis comes from
    (a) water
    (b) chlorophyll
    (c) carbon dioxide
    (d) glucose

    Answer:

    Photosynthesis, the process by which green plants and certain other organisms transform light energy into chemical energy.
    Chlorophyll absorbs ultraviolet rays and breaks the water molecule and forms oxygen. So, we get oxygen from the water molecule.
    6CO_{2} + 6 H_{2}O \rightarrow C_{6}H_{12}O_{6} + 6O_{2}

    Question:24

    The blood leaving the tissues becomes richer in
    (a) carbon dioxide
    (b) water
    (c) heamoglobin
    (d) oxygen

    Answer:

    Blood leaving the tissue is enriched with carbon dioxide. The aorta carries oxygenated blood from the heart to the organs. When this blood passes through the capillaries of body organs, it gives oxygen to the body cells.
    Hence the blood which reaches the tissue is enriched with oxygen which is absorbed by the tissue and the carbon dioxide from the cell is exchanged for oxygen.
    Deoxygenated blood (carrying CO_{2}) leaves the tissues and enters vena cava, from where they are again passed to the lungs for
    oxygenation.
    Hence option (a) is correct.

    Question:25

    Which of the following is an incorrect statement?
    (a) Organisms grow with time
    (b) Organisms must repair and maintain their structure
    (c) Movement of molecules does not take place among cells
    (d) Energy is essential for life processes

    Answer:

    Organisms grow with time - true
    Organisms must repair and maintain their structure – If they do not do so, they will no longer be alive. Hence the statement is true.
    Molecules move from one cell to another, for example, oxygen and food moves from cell to cell. Hence the statement is false.
    Energy is needed to carry out life processes, such as breaking down and building up molecules, transporting many molecules
    across cell membranes etc. Hence the statement is true.
    Hence option (c) is correct.

    Question:26

    The internal (cellular) energy reserve in autotrophs is
    (a) glycogen
    (b) protein
    (c) starch
    (d) fatty acid

    Answer:C

    Autotrophs comprise of green plants that photosynthesize their own food. In autotrophs the energy reserve is stored in the form of starch but in heterotrophs food is stored in the form of glycogen.
    Hence option (c) is correct.

    Question:27

    Which of the following equations is the summary of photosynthesis?
    (a) 6CO_{2} + 12H_{2}O \rightarrow C_{6}H_{12}O_{6} + 6O_{2} + 6H_{2}O
    (b) 6CO_{2} + H_{2}O + Sunlight \rightarrow C_{6}H_{12}O_{6} + O_{2} + 6H_{2}O
    (c) 6CO_{2} + 12H_{2}O + Chlorophyll + Sunlight \rightarrow C_{6}H_{12}O_{6} + 6O_{2}+ 6H_{2}O
    (d) 6CO_{2} + 12H_{2}O + Chlorophyll + Sunlight \rightarrow C_{6}H_{12}O_{6} + 6CO_{2}+ 6H_{2}O

    Answer: (c)

    Photosynthesis is a multi-step process that requires sunlight, carbon dioxide, and water as substrates.
    Summary of Photosynthesis in equation form
    6CO_{2} + 12H_{2}O + Chlorophyll + Sunlight \rightarrow C_{6}H_{12}O_{6} + 6O_{2}+ 6H_{2}O

    Question:28

    Choose the event that does not occur in photosynthesis
    (a) Absorption of light energy by chlorophyll
    (b) Reduction of carbon dioxide to carbohydrates
    (c) Oxidation of carbon to carbon dioxide
    (d) Conversion of light energy to chemical energy

    Answer: (c)

    Photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize nutrients from carbon dioxide and water. Carbon dioxide is used in photosynthesis for the production of food.
    Summary of Photosynthesis in equation form
    6CO_{2} + 12H_{2}O + Chlorophyll + Sunlight -\rightarrow C_{6}H{12}O_{6} + 6O_{2} + 6H_{2}O
    Absorption of light energy by chlorophyll takes place. Carbon dioxide is reduced and fixed in the form of carbohydrates. Reduction of carbon dioxide to carbohydrates also takes place. Oxygen is released from the water molecules. Oxidation of carbon to carbon dioxide does not take place. Conversion of light energy to chemical energy takes place.
    Hence option (c) is the correct answer.

    Question:29

    The opening and closing of the stomatal pore depends upon
    (a) oxygen
    (b) temperature
    (c) water in guard cells
    (d) concentration of CO_{2} in stomata

    Answer:

    Closing and opening of guard cells depends on the water content in the cells. If there is water in the cells the pores get opened and if there is less water, the cell shrinks and the pore gets closed.
    Hence option (c) is correct.

    Question:30

    (d) (i) and (iv)

    Answer:(b)

    Nitrogen is essential element to form proteins and it is observed in the form of nitrates, nitrites and urea. Sometimes we add urea in the soil and plants have adopted a lot to overcome nitrogen deficiency, for example, Carnivorous plants.
    Hence option (b) is correct.

    Question:31

    Which is the first enzyme to mix with food in the digestive tract?
    (a) Pepsin
    (b) Cellulase
    (c) Amylase
    (d) Trypsin

    Answer:(c)

    Salivary amylase is the first enzyme which is present in the saliva which gets mixed with the food in the mouth which starts breaking the starch in the food.
    • Salivary amylase breaks down starches into disaccharides
    • Pepsin breaks down proteins into large peptides
    • Trypsin continues the breakdown of protein
    Therefore option (C) is correct

    (c) (i) and (iv)
    (d) (ii) and (iii)

    Answer:(c)

    Fermentation is a form of anaerobic respiration. Pyruvate can be converted into ethanol and CO2 in yeast during fermentation. Since this process takes place in the absence of air (Oxygen), it is called anaerobic respiration.
    It takes place in cytoplasm.
    Hence (i) and (iv) are correct
    Therefore option (C) is correct

    Question:33

    Lack of oxygen in muscles often leads to cramps among cricketers. This results due to
    (a) conversion of pyruvate to ethanol
    (b) conversion of pyruvate to glucose
    (c) non conversion of glucose to pyruvate
    (d) conversion of pyruvate to lactic acid

    Answer:d

    • An excessively acid condition of the body fluids is known as acidosis.
    • Intracellular acidosis happens because of lactic acid accumulation and it has been viewed as the main source of skeletal muscle weariness.
    • Lactic acid is produced in the muscle from the metabolism of carbohydrates in the presence of low oxygen. This causes pain and weariness in muscles.
    Therefore option (D) is correct

    Question:34

    Choose the correct path of urine in our body
    (a) kidney \rightarrow ureter \rightarrow urethra \rightarrow urinary bladder
    (b) kidney \rightarrow urinary bladder \rightarrow urethra \rightarrow ureter
    (c) kidney \rightarrow ureters \rightarrow urinary bladder \rightarrow urethra
    (d) urinary bladder \rightarrow kidney \rightarrow ureter \rightarrow urethra

    Answer:C

    The urine formed in each kidney eventually enters a long tube ureter which connects kidney with urinary bladder. Urine is stored in urinary bladder which passes out through urethra.
    The urinary tract pathway includes:
    • Kidneys: They filter waste from the blood and produce urine
    • Ureters: Two thin tubes responsible for urine transfer from the kidney to the bladder
    • Bladder: A sac that holds the urine
    • Urethra: Tube that carries urine from the bladder out of the body
    Therefore option (C) is correct

    Question:35

    During deficiency of oxygen in tissues of human beings, pyruvic acid is converted into lactic acid in the
    (a) cytoplasm
    (b) chloroplast
    (c) mitochondria
    (d) golgi body

    Answer:

    The pyruvate formed from glycolysis goes into the Kreb's cycle as acetyl co-enzyme and creates a pool of chemical energy (ATP, NADH and FADH2). One of the substitute destinies of pyruvic acid in cellular respiration is that it can be changed over into lactic acid. This regularly happens in the cytoplasm of solid tissue under exhausting condition. Hence Pyruvic acid is converted into lactic acid in the cytoplasm of muscle cells during deficiency of oxygen in human beings.
    Therefore option (A) is correct

    e) Heterotrophs: The organisms which cannot prepare their own food and depend on other organisms for their nutritional needs
    f) Pepsin: The enzyme which is secreted by the gastric glands in the stomach that acts on proteins

    Question:37

    “All plants give out oxygen during day and carbon dioxide during night”. Do you agree with this statement? Give reason.

    Answer:

    “All plants give out oxygen during day and carbon dioxide during night”
    The above statement is correct. All plants produce oxygen during day time as photosynthesis takes place in the presence of sunlight and oxygen is a byproduct of photosynthesis. At night time, photosynthesis does not takes place and the normal cellular respiration of plants will be releasing carbon dioxide.

    Question:38

    How do the guard cells regulate opening and closing of stomatal pores?

    Answer:

    Guard cells regulate the opening and closing of the stomatal pores by swelling and shrinking normally. Guard cells will swell by absorbing water and opens the pores and by shrinking the guard cells will close the pores. When guard cells are turgid, stomatal pore is open while in flaccid conditions, the stomatal aperture closes.

    Question:39

    Two green plants are kept separately in oxygen free containers, one in the dark and the other in continuous light. Which one will live longer? Give reasons.

    Answer:

    The plant placed in the dark will die as it cannot perform photosynthesis and within a few time, the whole chamber will be filled with carbon dioxide. On the other hand the plant in the open sunlight will perform photosynthesis (and produces oxygen required for its respiration) and this plant lives for a longer duration.

    Question:40

    If a plant is releasing carbon dioxide and taking in oxygen during the day, does it mean that there is no photosynthesis occurring? Justify your answer.

    Answer:

    Photosynthesis and respiration are two independent processes.
    • Respiration: Process of oxidation of food substances. It releases carbon dioxide and takes place throughout the day.
    • Photosynthesis: Process of fixing the atmospheric carbon dioxide into organic compounds (carbohydrates). It releases oxygen gas as a by-product.
    Photosynthesis takes place in presence of Sunlight only. If a plant is releasing carbon dioxide and taking in oxygen during the day, it does not mean that there is no photosynthesis occurring. It means that the rate of photosynthesis is slow.

    Question:41

    Why do fishes die when taken out of water?

    Answer:

    Respiration in fishes takes place using gills.
    Gills can only absorb oxygen which is dissolved in water and cannot take oxygen which is present in atmosphere. At the point when the water enters the fish through its mouth, the oxygen is taken inside and carbon dioxide is given out through the gills.
    So when the fish is taken out of water, the supply of oxygen is cut down and they cannot breathe for long. That's the reason fishes die when we take them out of water

    Question:42

    Answer:

    Autotrophs Heterotrophs
    1. Can prepare their own food 1. heterotrophs depend on
    with the help of sunlight, air, and water autotrophs and other organisms for
    nutrition.
    2. Autotrophs are the primary producers 2. Heterotrophs are the consumers
    3. They are placed first in the food chain 3. They are placed at secondary and tertiary levels.
    4. Examples: Plants, algae and 4. Examples: Animals like cow, dog,
    few bacteria lion, horse, etc.

    Question:43

    Is ‘nutrition’ a necessity for an organism? Discuss.

    Answer:

    Yes, all living organisms need nutrition as it provides the energy required for all the metabolic processes in a living organism.
    Nutrition is needed:
    (a) For metabolic processes in the body, it serves as an energy source
    (b) Repair and maintain the existing cells and supports growth of new cells.
    (c) To give opposition against various diseases.

    Question:44

    What would happen if green plants disappear from earth?

    Answer:

    Green plants are predominant autotrophs which provide food for all the heterotrophs on this planet. These organisms occupy the first trophic level in the food chain and serve as source of food and energy for all other organisms of higher trophic levels (heterotrophs). They also balance the carbon dioxide and oxygen levels in the atmosphere so if green plants disappear then the life on this planet will cease to exist.

    Question:45

    Leaves of a healthy potted plant were coated with vaseline. Will this plant remain healthy for long? Give reasons for your answer.

    Answer:

    When the leaves of a healthy plant are coated with vaseline it will block the stomatal pores. This will not allow the oxygen and carbon dioxide exchange so the plant will not live healthy for a long time. Plant will not be able to take in oxygen for respiration and carbon dioxide for photosynthesis.

    Question:49

    What are the adaptations of leaf for photosynthesis?

    Answer:

    Adaptation of leaves:
    1. Large surface area for the maximum absorption of light.
    2. The presence of numerous stomatal pores for carbon dioxide and oxygen exchange.
    3. Presence of chlorophyll to absorb light and making photosynthesis possible.
    4. Extensive network of veins transport substances to and fro quickly from mesophyll cells.

    Question:50

    Why is small intestine in herbivores longer than in carnivores?

    Answer:

    Herbivores get their nourishment from plants which thus makes cellulose main component of their diet Herbivorous animals which eat grass need longer intestine to absorb the cellulose in the food whereas meat-eating animals can digest as there is no cellulose to digest.
    Cellulose digestion is a long process and is done by intestinal ruminant bacteria present in gut of herbivores.

    Question:51

    What will happen if mucus is not secreted by the gastric glands?

    Answer:

    Gastric juice is produced by the gastric glands of stomach. It contains pepsinogen, HCl, and mucus. HCl imparts highly acidic pH to stomach which thus bolsters transformation of idle pepsinogen into dynamic pepsin.
    Mucus protects the inner lining of stomach from the HCl produced by gastric glands. If mucus is not released it will lead to damage of the inner lining of stomach causing acidity and ulcers.

    Question:52

    What is the significance of emulsification of fats?

    Answer:

    Emulsification refers to the breakdown of fat globules in the duodenum into tiny droplets. This provides a larger surface area on which the enzyme pancreatic lipase can act to digest the fats into fatty acids and glycerol. Hence, it facilitates digestion of fats.

    Question:53

    What causes movement of food inside the alimentary canal?

    Answer:

    Peristalsis causes movement of food inside the alimentary canal.
    It is the rhythmic contraction and relaxation of muscles which pushes the food forward in in the alimentary canal.

    Question:54

    Why does absorption of digested food occur mainly in the small intestine?

    Answer:

    Digestion of food takes place in the small intestine because it has small projections on the surface called as villi which increases the surface area. The small intestine is richly supplied with blood vessels which takes the absorbed food to all the cells of the body.

    Question:55

    Match Group (A) with Group (B)
    Group (A) Group (B)
    (a) Autotrophic nutrition (i) Leech
    (b) Heterotrophic nutrition (ii) Paramecium
    (c) Parasitic nutrition (iii) Deer
    (d) Digestion in food vacuoles (iv) Green plant

    Answer:


    Autotropic Nutrition: Consists of the organisms which make their own food. Example, plants. These organisms are known as autotrophs.
    Heterotopic Nutrition: Consists of the organisms which depend on autotrophs for nutrition. Example, deer. These organisms are known as heterotrophs.
    Parasitic nutrition: Consists of the organisms that feed on a living host for nutrition. Example, leech. These organisms are known as parasites.
    Digestion of food in vacuoles is a mode of digestion which is prominent in microorganisms. Example, Paramecium.

    Question:56

    Why is the rate of breathing in aquatic organisms much faster than in terrestrial organisms?

    Answer:

    Fishes absorb dissolved oxygen from water through gills. As the amount of dissolved oxygen in water is low and to compensate that low oxygen, the organisms has faster breathing rate as compared to that of terrestrial organisms.

    Question:57

    Why is blood circulation in human heart called double circulation?

    Answer:

    In humans, blood passes through the heart twice during one complete cardiac cycle of the body. Once through the right ventricle to the left auricle of the heart, called pulmonary circulation. Second through the left ventricle to right auricle of the heart through body tissues, called systemic circulation.
    Advantages of double circulation:
    • Maintains higher blood pressure
    • Allows greater flow of blood to the tissues.
    • Creates more pressure to pump blood to other organs.
    • Produces a large amount of energy to maintain life processes.

    Question:58

    What is the advantage of having four chambered heart?

    Answer:

    Four chambers of heart are as follows:


    Advantages of four chambered heart:
    1) Four chambered heart ensures the separation of oxygenated and deoxygenated blood
    2) Highly efficient in supplying oxygenated blood to all parts of body
    3) This is prominent in warm blood animals which have high energy needs.
    4) Maintains higher blood pressure and allows greater flow of blood to the tissue

    Question:59

    Mention the major events during photosynthesis

    Answer:

    Photosynthesis is the process by which green plants and certain other organisms transform light energy into chemical energy.
    It is a multi-step process that requires sunlight, carbon dioxide, and water as substrates.
    Summary of Photosynthesis in equation form
    6CO_{2} + 12H_{2}O + Chlorophyll + Sunlight \rightarrow C_{6}H_{12}O_{6} + 6O_{2} + 6H_{2}O
    Major Events of Photosynthesis are as follows:
    1) Absorption of sunlight by chlorophyll
    2) Transfer of electrons
    3) Generation of ATP: Conversion of light energy into chemical energy and splitting of water molecule into hydrogen and oxygen.
    4) Carbon fixation: Reduction of Carbon dioxide to carbohydrates.

    Question:60

    In each of the following situations what happens to the rate of photosynthesis?
    (a) Cloudy days
    (b) No rainfall in the area
    (c) Good manuring in the area
    (d) Stomata get blocked due to dust

    Answer:

    Photosynthesis is the process by which green plants and certain other organisms transform light energy into chemical energy.
    It is a multi-step process that requires sunlight, carbon dioxide, and water as substrates.
    Summary of Photosynthesis in equation form
    6CO_{2}+12H_{2}O+Chlorophyll+Sunlight \rightarrow C_{6}H_{12}O_{6}+6O_{2}+6H_{2}O

    (a) Cloudy days: The rate of photosynthesis decreases as the sunlight is low.
    As the intensity of light decreases, the rate of light-dependent reactions of photosynthesis and in turn, the rate of
    photosynthesis decreases.

    (b) No rainfall in the area: The rate of photosynthesis decreases as the water is needed for photosynthesis. which gets broken into oxygen and hydrogen which later converts in to carbohydrates.

    (c) Good Manuring in the area: The rate of photosynthesis increases as plants need raw minerals such as Fe, N, Mg, P….etc. for building their body and manuring increases raw minerals which further increases the rate of photosynthesis.

    (d)CO_{2} gas enters the leaves through stomata. If stomata get blocked due to dust, CO_{2} gets blocked and hence rate of photosynthesis decreases.

    Question:61

    Name the energy currency in the living organisms. When and where is it produced?

    Answer:

    Energy currency of living organisms is ATP (Adenosine triphosphate).
    It is produced in mitochondria at the end of respiration where ADP (Adenosine diphosphate) is converted to ATP (Adenosine triphosphate).

    Question:62

    What is common for cuscuta, ticks and leeches?

    Answer:

    Cuscuta, ticks and leeches all are parasites with parasitic mode of nutrition where the organism absorbs food from the host without giving any benefit to the host. Parasites are harmful to host organism.

    Question:63

    Explain the role of mouth in digestion of food.

    Answer:

    Role of mouth in digestion of food
    1) Teeth cut the food and increases the surface area of food to absorb enzymes.
    2) The salivary glands in mouth secrets saliva which contains an enzyme called salivary amylase which digests the starch present in the food (chemical digestion)
    3) Tongue helps in thorough mixing of food with saliva

    Question:65

    Salivary amylase is present in saliva which helps in digesting starch in food.
    Pepsin secreted by gastric glands which helps in protein digestion.
    Bile is secreted by liver which contains lipase which helps in emulsification of fats.

    Question:67

    Why do veins have thin walls as compared to arteries?

    Answer:

    Blood emerges from heart with a high pressure. Arteries are thick walled because they are responsible to carry high pressure blood to other body organs.
    Compared to arteries, veins carry deoxygenated blood from all body parts back to the heart. The blood flowing is not under high pressure therefore veins are thin-walled blood vessels.

    Question:68

    What will happen if platelets were absent in the blood?

    Answer:

    Main objective of platelets is to form a blood clot in case of an injury. In the absence of platelets, the process of clotting will not take place which will lead to blood loss. Excessive loss of blood might be fatal in many cases.

    Question:69

    Plants have low energy needs as compared to animals. Explain.

    Answer:

    All the movements in plants are cellular. Plants do not move physically as humans or animals. Sclerenchyma is the tissue which makes the plant hard and stiff. It is known as a supporting tissue. They provide strength to the plant making energy requirements low for the plant.
    On the other hand, animals require more energy because they need to move from one place to another for food, shelter, mating etc.

    Question:70

    Why and how does water enter continuously into the root xylem?

    Answer:

    Water is required by plants for photosynthesis. Transpiration is the process of water movement through a plant and its evaporation.
    Transpiration pull makes the water enter continuously into the root xylem. The water is lost to atmosphere by the stomata. This water is pulled from the xylem to the roots to the leaves.
    Cells of roots are in close contact with soil thus effectively take up particles by dispersion. The ion-concentration increments inside the root and henceforth osmotic pressure expands the development of water from soil into root which happens constantly.

    Question:71

    Why is transpiration important for plants?

    Answer:

    Transpiration is the process of water movement through a plant and its evaporation.

    1. It helps in absorption of water
    2. It helps in upward movement of water and minerals from root system to shoot system.
      It helps in thermoregulation, i.e., maintaining the internal temperature of the plant therefore preventing it from heating up.

    Question:72

    How do leaves of plants help in excretion?

    Answer:

    1) Stomata are the tiny openings present on the epidermis of leaves. Gaseous waste of respiration and photosynthesis are removed through stomata.
    2) In many plants, waste material is stored in the vacuoles of mesophyll cells and epidermal cells. This waste is excreted along with the older leaves when they fall.

    Question:73

    Explain the process of nutrition in Amoeba.
    Answer:

    The process of obtaining food by amoeba is called phagocytosis. Various steps of involved phagocytosis in Amoeba are as follows:
    1. Ingestion: Food ingests particle by forming temporary finger like structures called pseudopodia. Food is engulfed by forming vacuole around it.
    2. Digestion: Food particles are broken by digestive enzymes inside the food vacuole.
    3. Absorption: Digested food gets diffused into cytoplasm and the food vacuole disappears after digestion.
    4. Egestion: Removal of undigested food from amoeba.

    Question:74

    Describe the alimentary canal of man.

    Answer:

    Alimentary canal of man: It measures about 8 to 10 meters starting from mouth and extends till anus.
    1. Mouth: It consists of oral cavity which contains the lips, inside lining of the lips and cheeks, teeth, gums, the front two-thirds of the tongue, the floor of the mouth below the tongue, and the bony roof of the mouth.
      Food in broken into small parts and salivary glands secrete saliva which is mixed with the food by the tongue.
    2. Pharynx: Oral cavity opens into pharynx. Swallowing mechanism guides masticated food down to stomach.
    3. Oesophagus: A muscular tube connecting pharynx to stomach. Muscular movement in the oesophagus moves the food to stomach.
    4. Stomach: It is a J-shaped sac like muscular structure where masticated food is mixed with gastric juices which are secreted by the lining of stomach.
    5. Small intestine: It is a tube like structure about 6 meters where pancreatic juice and bile juice gets mixed. Small intestine is rich with blood vessels where chemical digestion happens and the food is absorbed and delivered to all the parts of body.
    6. Large intestine: Unabsorbed food is sent to large intestine where water from is absorbed from this food. Rest of it is removed from the body via anus. The exit of waste material is regulated by anal sphincter.

    Question:75

    Explain the process of breathing in man.

    Answer:

    Inspiration: When we breathe in, diaphragm contracts and lungs expands. When air is sucked in from the outside into the lungs, lungs get filled with air.
    Gaseous Exchange: Hemoglobin in red blood cells binds with oxygen and delivers to all the cells and takes carbon dioxide from the cells. Carbon dioxide rich hemoglobin comes back to lungs where carbon dioxide is exchanged with oxygen on alveolar surface.
    Expiration: When we breathe out, our lungs contract and push the carbon dioxide rich air (where the carbon dioxide from the cells has reached the alveoli and get exchanged for oxygen)

    Question:76

    Explain the importance of soil for plant growth.

    Answer:

    Importance of soil for plant growth.
    1) Soil provides the point of anchorage for all the plants.
    2) Soil is the reservoir for water and minerals which are essential for all the metabolic activities of a plant.
    3) Roots of plant absorb oxygen diffused in soil for respiration purposes.
    4) Some plants have symbiotic relationship with bacteria and fungi in soil to fulfil their nitrogen requirements.

    Question:78

    How do carbohydrates, proteins and fats get digested in human beings?

    Answer:

    Digestion of carbohydrates:
    Oral cavity: Starch is broken down into maltose by salivary amylase present in the saliva.
    Small intestine:
    Remaining starch is broken down into maltose by pancreatic amylase present in the pancreatic juice
    Maltose is broken down into glucose units by Maltase of intestinal juice.

    Digestion of Proteins:
    Proteins digestion does not start in oral cavity as mouth does not have any digesting enzyme for proteins.
    Stomach: Stomach secretes pepsin which is a protein digesting enzyme. In its inactive form, pepsin is called as pepsinogen.
    Upon exposure to HCl, pepsinogen gets converted to active pepsin.
    Pepsin starts protein digestion into small peptides.

    Small intestine:
    Trypsin and chymotrypsin digest proteins into peptides. Pancreatic juice secretes Trypsinogen, chymotripsinogen (inactive from of trypsin).
    Peptidases of intestinal juice digest the peptides into amino acids.

    Digestion of Fats:
    Small intestine:
    Emulsification of large globules of fats into smaller droplets by bile salt.
    Pancreatic lipase digests the emulsified fat globules into glycerol and fatty acids.
    Glycerol and fatty acids enter the villi cells where they are rejoined and packaged as lipoprotein droplets before entering the lacteals.

    Question:79

    Explain the mechanism of photosynthesis.

    Answer:

    The process in which green plants convert carbon dioxide and water into glucose in the presence of chlorophyll and sunlight is called photosynthesis.
    6CO_{2} + 12H_{2}O + Chlorophyll + Sunlight \rightarrow C_{6}H_{12}O_{6} + 6O_{2} + 6H_{2}O
    Step by step process of photosynthesis
    1) Sun light is absorbed by the green pigment called chlorophyll
    2) The light is converted into chemical energy
    3) Water molecule is split into hydrogen and oxygen. Oxygen produced by splitting the water molecule is released into
    atmosphere
    4) Hydrogen formed by splitting water molecule is utilized for reduction of carbon dioxide to form carbohydrate (glucose)
    5) The extra glucose is stored as starch in the leaves of the plant

    Question:80

    Explain the three pathways of breakdown in living organisms.

    Answer:

    Glucose is a 6-carbon molecule, while pyruvate is a 3-carbon molecule. In all organisms, glucose is first converted into pyruvate in the cytoplasm.
    Further breakdown of pyruvate can happen in any of the following ways:
    • In Yeast: Breakdown of pyruvate takes place in absence of oxygen. Pyruvate is broken down into ethanol and carbon dioxide. It is called anaerobic respiration.
    • In mitochondria: Breakdown of pyruvate takes place in presence of oxygen. Pyruvate is broken down into carbon dioxide and water. It is called aerobic respiration. It is found in most of the living beings.
    • In muscle cells: The energy demand from muscle cells suddenly increases during strenuous physical activities. This is compensated by anaerobic respiration in muscle cells. In this, pyruvate is broken down into lactic acid.

    Question:81

    Describe the flow of blood through the heart of human beings.

    Answer:

    Flow of blood through heart:
    Oxygen rich blood reaches thin-walled upper chamber of heart on the left, the left atrium from lungs. Left atrium relaxes and collects blood; then contracts to enter the next chamber (the left ventricle), which expands so blood gets collected in to it. Muscular ventricle contracts and pumps oxygen rich blood to all parts of body.
    Deoxygenated blood from the body comes to the upper chamber on the right side (the right atrium), and it expands. As the right atrium contracts, the corresponding lower chamber (the right ventricle) relaxes. This transfers blood to the right ventricle which in turn pumps into the lungs for oxygenation. This process is repeated continuously to fulfil the oxygen needs of the body.
    The blood circulatory system in humans is double circulation as blood reaches heart twice in one complete cycle.
    1) The pathway of blood from the heart to lungs and back to the heart is called the pulmonary circulation.
    2) The pathway of blood from the heart to the rest of the body and back to the heart is called as systemic circulation.
    Systemic Circulation + Pulmonary Circulation = Double Circulation

    Question:82

    Describe the process of urine formation in kidneys.

    Answer:
    The excretory system of human beings includes a pair of kidneys, a pair of ureters, a urinary bladder and a urethra. Kidneys are located in the abdomen, one on either side of the backbone. Urine produced in the kidneys passes through the ureters into the urinary bladder where it is stored until it is released through the urethra.
    Each kidney has a cluster of very thin-walled blood capillaries. Each capillary cluster in the kidney is associated with the cup-shaped end of a tube that collects the filtered urine. Each kidney has large numbers of these filtration units called nephrons packed close together. Some substances in the initial filtrate, such as glucose, amino acids, salts and a major amount of water, are selectively re-absorbed as the urine flows along the tube.
    The amount of water reabsorbed depends on how much excess water there is in the body, and on how much of dissolved waste there is to be excreted. The urine forming in each kidney eventually enters a long tube, the ureter, which connects the kidneys with the urinary bladder. Urine is stored in the urinary bladder until the pressure of the expanded bladder leads to the urge to pass it out through the urethra.
