Life Processes Class 10 questions and answers topic 5.1 - What are life processes: Page Number 81
Q.1. Why is diffusion insufficient to meet the oxygen requirements of multicellular organisms like humans?
Answer:
Multicellular Organisms have complex systems each assigned to a specific task. These systems comprise of tissues which comprise millions of cells that require a continuous supply of oxygen to meet the functional requirements and since all these cells are not in contact with the environment around the organism diffusion is insufficient to meet the oxygen requirements of multicellular organisms.
Q. 2. What criteria do we use to decide whether something is alive?
Answer:
The presence of a cellular structure and processes like respiration, excretion, reproduction and growth are criteria we use to decide whether something is alive or not. In some cases, movement can also be the criteria for the same.
Q. 3. What are the outside raw materials used by an organism?
Answer:
The outside raw materials used by an organism are:
1. Carbon-based compounds e.g. carbohydrates, fats etc. which provide energy for cellular processes.
2. Water is the medium for all intracellular reactions and the medium in which all of the transportation of materials takes place.
3. Oxygen which is used for aerobic respiration.
4. Some other minerals are also taken from outside as raw materials like iron, sodium, phosphorus etc.
Q. 4. What processes would you consider essential for maintaining life?
Answer:
Processes that are essential for maintaining life are respiration, nutrition, transportation, excretion and control and coordination.
Life Processes Class 10 questions and answers Chapter 5 Life Processes, Topic 5.2 Nutrition: Page Number 87
Q. 1. What are the differences between autotrophic nutrition and heterotrophic nutrition?
Answer:
The differences between autotrophic nutrition and heterotrophic nutrition are given below:
| Autotrophic Nutrition | Heterotrophic Nutrition |
| (i) Food or source of energy is synthesized by the organism itself by using the energy from sunlight, using simple molecules like H2O and CO2. | (i) The organism is dependent on other organisms for food or a source of energy as Heterotrophic organisms cannot prepare their food. |
| (ii) A green pigment called chlorophyll is necessary as it entraps the energy from sunlight. | (ii) No such pigment is required in this mode of nutrition. |
| (iii) All green plants and bacteria have this mode of nutrition, | (iii) All animals and some fungi have this mode of nutrition. |
Q. 2. Where do plants get each of the raw materials required for photosynthesis?
AnsPlantse plants require several raw materials and energy for photosynthesis.
(i) Plants acquire CO2 from the atmosphere using their stomata.
(ii) Plants absorb H2O from the soil using their roots.
(iii) The energy required for photosynthesis is obtained from sunlight.
(iv) Chlorophyll is present in the chloroplast, which is found in the green parts of the plants but especially in the leaves.
Q. 3. What is the role of the acid in our stomach?
Answer:
The Hydrochloric acid present in our stomach has 3 main roles.
(i) It dissolves bits of food that have been chewed.
(ii) Provides an acidic medium which is essential for the activation of the enzyme pepsin which is essential for digestion.
(iii) The acid kills bacteria present in the stomach.
Q. 4. What is the function of digestive enzymes?
Answer:
The food we eat consists of very complex molecules that cannot be used for taking up energy and therefore these molecules have to be broken down into simple molecules.
The process of breaking down these molecules is a very complex chemical process and requires a very long time and this is where the digestive enzymes come in. They act as bio-catalysts and speed up the chemical reactions involving the breakdown of these molecules so that they can be absorbed by the cells and energy can be derived from them.
Q. 5. How is the small intestine designed to absorb digested food?
Answer:
The design of the small intestine is such that it provides the maximum area for the absorption of digested food and its transportation to different parts of our body through blood vessels.
For these purposes, the inner lining of the small intestine has finger-like projections called villi providing a large surface area for absorption and the small intestine is supplied richly with blood vessels for the efficient transportation of the absorbed food.
NCERT Solutions for Class 10 Science Chapter 5 Life Processes Topic 5.3 Respiration: Page Number 91
Q. 1. What advantage over an aquatic organism does a terrestrial organism have in obtaining oxygen for respiration?
Answer:
Terrestrial organisms breathe in oxygen for respiration directly from the environment as opposed to the aquatic organisms which have to use oxygen dissolved in water.
The concentration of dissolved oxygen in water is much lesser than that present in the air and therefore aquatic organisms have to have a much faster breathing rate than terrestrial organisms for the sufficient supply of oxygen.
In the course of evolution, aquatic organisms have also developed special body parts for the efficient absorption of oxygen dissolved in water.
Q. 2. What are the different ways in which glucose is oxidised to provide energy in various organisms?
Answer:
First, the glucose is broken down into a 3-carbon molecule called Pyruvate in the cytoplasm of the cell in a process called glycolysis.
The process can further proceed using three different pathways depending on the amount of oxygen present.
- In the presence of sufficient Oxygen, Pyruvate molecules are broken down into Water and Carbon dioxide and Energy is released. This process is called aerobic respiration.
- In the lack of oxygen, Pyruvate molecules are converted into lactic acid and energy is released. This takes place in our muscles especially while exercising. The lactic acid thus produced causes cramps in our muscles.
- In the total absence of Oxygen Pyruvate molecules are broken down into Ethanol and Carbon dioxide, and Energy is released. This process is called anaerobic respiration and takes place in yeast cells.
Q. 3. How are oxygen and carbon dioxide transported in human beings?
Answer:
Oxygen and carbon dioxide are transported by human beings.
(i) The transportation of oxygen from the lungs to other body parts takes place through our blood vessels. Oxygen has low solubility and therefore cannot be transported directly in plasma. The red blood cells contain a pigment called Haemoglobin with which the Oxygen molecules stick once they are absorbed through our lungs. These red blood cells carry the oxygen to the oxygen-deficient parts and then release it to be used for respiration.
(ii) Carbon dioxide is the by-product of respiration and has to be eliminated from our bodies. Due to its high solubility in water, it is directly transported from various body parts to the lungs through the plasma of our blood only and is released into the environment by exhaling.
Q. 4. How are the lungs designed in human beings to maximize the area for the exchange of gases?
Answer:
The air passages in our lungs dived into several smaller passages called bronchi.
These bronchi further divide into even smaller passages called bronchioles which terminate into very small baloon-like structures called Alveoli. Each lung consists of a million alveoli as they are very small in size.
These alveoli have very soft lining optimum for absorption of Oxygen through vessels and their large number provides a very large surface area for the absorption of oxygen.
Life Processes Class 10 Questions and Answers, Topic 5.4 Transportation: Page Number 96
Answer:
The transport/circulatory system in human beings consists of the following three parts:
(i) Blood: The blood is the medium for transportation of all kinds of materials like oxygen, carbon dioxide, digested food and waste material from one part of the body to the other.
(ii) Blood Vessels: The intricate network of blood vessels consisting of arteries, veins, and capillaries run through the entire body and the transportation of materials like oxygen, carbon dioxide, digested food and waste material from one part of the body to the other takes place through the blood vessels only.
(iii) Heart: The heart pumps the blood through the blood vessels. Deoxygenated blood containing Carbon dioxide reaches the heart from different parts of the body and is pumped to the lungs through veins for releasing carbon dioxide and absorption of oxygen. Oxygen-rich blood reaches the heart from the lungs and is pumped through arteries to the tissues and organs where oxygen is required.
Q. 2. Why is it necessary to separate oxygenated and deoxygenated blood in mammals and birds?
Answer:
Mammals and birds continuously require oxygen in all body parts so aerobic respiration takes place so that heat is continuously generated to maintain the body temperature required.
To efficiently facilitate this process it is necessary to separate oxygenated and deoxygenated blood in mammals and birds.
Q. 3. What are the components of the transport system in highly organised plants?
Answer:
In highly organised plants the transport system consists of the following two components.
(i) Xylem: The xylem consists of a network of vessels and elongated cells called tracheids. The xylem tissues transport the water and other minerals absorbed from the soil by the roots to different parts of the plant.
(ii) Phloem: The Phloem tissue transports the soluble organic compounds (food) synthesized during photosynthesis from the leaves to other parts of the plant.
Q. 4. How are water and minerals transported in plants?
Answer:
The roots of a plant have hair-like structures called root hair. The root hair provides a large area for the absorption of water and other dissolved minerals from the soil into the roots through diffusion.
The absorbed water and minerals travel from cell to cell by osmosis and reach the root xylem. From the root xylem the, is transported into the stem xylem. The branched xylem network from the stem leaves through the stalk of the leaf and through this network of xylem tissue water and minerals are transported in plants.
Q. 5. How is food transported in plants?
Answer:
The transportation of food material in plants takes place through the phloem tissue. This transportation of food material in plants requires energy which is obtained by using ATP. This release of energy causes a different rise in the osmotic pressure in the tissues surrounding the phloem and causes water to move in the phloem tissue through osmosis.
This further increases the osmotic pressure in the phloem and drives the circulation of water-containing food material to all parts of the plant through the phloem tissue.
Life Processes Class 10 questions and answers topic 5.5 Excretion: Page Number 98
Q. 1. Describe the structure and functioning of nephrons
Answer:
The nephrons are the basic filtering unit of our excretion system.
Each nephron has a Bowman's capsule which is a cup-shaped bag having a bundle of vessels called the glomerulus. Impure blood from all parts of our body enters the glomerulus through the renal artery and the impurities are filtered, The rest of the nephron is coiled and their sugars, amino acids, excess water, etc. which are important for the body are re-absorbed. The filtrate left is urine containing all the waste generated in the body e.g. urea. This urine is excreted through the urethra.
Q. 2. What are the methods used by plants to get rid of excretory products?
Answer:
The following methods are used by plants to get rid of excretory products.
(i) Gaseous wastes are released in the atmosphere through the stomata in leaves and lenticels in stems.
(ii) Solid and liquid wastes are excreted by leaves shedding, bark peeling off and through fruits.
(iii) Waste products are excreted by releasing them through gums and resins.
(iv) Some waste products are directly released into the soil by the roots
Q. 3. How is the amount of urine produced regulated?
Answer:
The amount of urine produced depends on the following:
(i) Amount of water ingested. If a large amount of water is ingested regularly large amounts of dilute urine will be produced. In case sufficient water is not ingested urine produced will be less in amount but will have a high concentration of nitrogenous wastes and this is harmful to the excretory system and the body.
(ii) The amount of waste produced in the body decides how much urine is to be excreted.
(iii) The release of some hormones also regulates the amount of urine produced.

(b) is the correct answer.
Q. 5. How are fats digested in our bodies? Where does this process take place?
Answer:
Digestion of fat takes place in the small intestine. Fat reaches the small intestine in the form of large globules.
The liver releases bile juice which emulsifies the fat i.e., it breaks down the large globules into smaller globules thus increasing the area on which pancreatic juice called lipase acts and breaks down the globules into molecules.
The small intestine then releases juices which convert these fat molecules into fatty acids and glycerol which can be used by the body.
Q. 6. What is the role of saliva in the digestion of food?
Answer:
Saliva contains an enzyme called salivary amylase that starts the process of digestion in the mouth itself by breaking down starch into sugar molecules like maltose.
Saliva helps in keeping the mouth clean, moistened and lubricated thus aiding in chewing food so that large pieces are broken down into small bits.
Q. 7. What are the necessary conditions for autotrophic nutrition and what are its byproducts?
Answer:
The necessary conditions for autotrophic nutrition are the following:
(i) Supply of carbon dioxide which is the raw material for this mode of nutrition.
(ii) Presence of sunlight which is the source of energy.
(iii) Presence of chlorophyll in the leaves which entraps the energy from sunlight.
(iv) Supply of water.
The byproduct of autotrophic nutrition is Oxygen.
Answer:
Differences between aerobic and anaerobic respiration are mentioned below:
| Aerobic Respiration | Anaerobic Respiration |
| (i) It takes place in the presence of Oxygen. | (i) It takes place in the absence of Oxygen. |
| (ii) It involves the exchange of gases between organisms and surroundings. | (ii) It does not involve the exchange of gases between organisms and surroundings |
| (iii) The end products are always Carbon dioxide and water. | (iii) The end products vary. |
| (iv) Complete breakdown of glucose molecules takes place. | (iv) Partial breakdown of glucose molecules takes place. |
| (v) More energy is produced per molecule of glucose broken down. | (v) Less energy is produced per molecule of glucose broken down. |
| (vi) Takes place in the cytoplasm and mitochondria. | (vi) Takes place only in cytoplasm. |
Anaerobic respiration takes place in some worms, water-logged plants, yeast and some bacteria.
Q. 9. How are the alveoli designed to maximise the exchange of gases?
Answer: Alveoli are thin-walled and are richly supplied with blood vessels to maximise the exchange of gases.
The alveoli have a baloon-like structure thus providing a large surface area available for the exchange of gases.
Q. 10. What would be the consequences of a deficiency of haemoglobin in our bodies?
Answer:
As the function of Haemoglobin is to transport haemoglobin to the lungs and balloon-like parts of the body its deficiency would cause levels of Oxygen to be lesser than the required level thus rendering the body incapable of producing the required amount of energy and thus would make a person feel tired most of the times and would also affect his immunity thus making him susceptible to diseases.
Q. 11. Describe the double circulation of blood in human beings. Why is it necessary?
Answer:
Deoxygenated blood rich in carbon dioxide and deficient in oxygen reaches the heart through a network of veins enters the network through the vena cava and is brought into the right atrium. From the right atrium, the deoxygenated blood goes to the right ventricle from where it is pumped to the lungs through the pulmonary artery where carbon dioxide is released into the environment and oxygen is absorbed in the blood. From the lungs, the oxygenated blood enters the left atrium through the pulmonary vein. From the left atrium, the blood enters the left ventricle from where it is pumped to all parts of the body to facilitate the supply of oxygen.
This double circulation in human beings helps maintain high oxygen levels in blood which facilitates sufficient aerobic respiration for the generation of sufficient heat to maintain the body temperature.
Q. 12. What are the differences between the transport of materials in the xylem and phloem?
Answer:
| Xylem | Phloem |
| (i) In Xylem water and minerals absorbed from the soil by the roots are transported to other parts of the plant. | (i) In Phloem food synthesized through photosynthesis is transported from the leaves to other parts of the plant. |
| (ii) In Xylem transport of material takes place through vessels and tracheids which are dead tissue. | (ii) In Phloem transport of material takes place through sieve tubes and companion cells which are living cells. |
| (iii) In the xylem upward movement of water is produced by transpirational pull occurring due to the evaporation of water from the leaves | (iii) In Phloem material is transported due to the difference in osmotic pressure created using energy from ATP. |
Answer:
| Alveoli | Nephron |
| (i) The alveoli are the functional unit of the lungs. | (ii) Nephron is the functional unit of the Kidneys. |
| (ii) A lung has about 300 million alveoli. | (ii) A kidney has about a million nephrons. |
| (iii) Alveoli provide a very large surface for the exchange of gaseous materials to take place. | (iii) The Surface area of Nephrons is not very large. |
| (iv) The exchange of carbon dioxide and oxygen takes place through alveoli. | (iv) The absorption of water, amino acids, sugar molecules etc. takes place in the Nephron. |

Nutrition
Respiration
Transportation
Excretion
4. How does blood circulation occur in humans?
In humans, blood circulation occurs through the double circulatory system, which includes the pulmonary circulation (between the heart and lungs) and systemic circulation (between the heart and the rest of the body). The heart pumps oxygenated blood to body tissues and deoxygenated blood to the lungs for oxygenation. This continuous circulation ensures the transport of oxygen, nutrients, and waste products throughout the body.
5. What are the four life processes in Class 10 Science Chapter 5?
The four life processes covered in Class 10 Science Chapter 5 (Life Processes) are:
- Nutrition – The process of obtaining and utilizing food for energy and growth (autotrophic in plants and heterotrophic in animals).
- Respiration – The breakdown of glucose to release energy, either aerobically (with oxygen) or anaerobically (without oxygen).
- Transportation – The movement of nutrients, gases, and waste products within the body (circulatory system in animals, xylem and phloem in plants).
- Excretion – The removal of metabolic waste products (e.g., kidneys in humans remove urea, while plants excrete through stomata and resins).
6. What is the process of nutrition in plants and animals?
Nutrition in Plants: Plants exhibit autotrophic nutrition, wherein they synthesize their own food by the process of photosynthesis using sunlight, carbon dioxide, and water. It takes place in chloroplasts and yields glucose and oxygen.
Nutrition in Animals: Animals exhibit heterotrophic nutrition, wherein they take in other organisms as food. The process involves ingestion, digestion, absorption, assimilation, and egestion to acquire and utilize the nutrients.
7. How does respiration occur in humans?
In humans, respiration is via the respiratory system, where oxygen is breathed into the lungs and diffuses into the blood. The oxygen is delivered to body cells for aerobic respiration, where glucose is metabolized to release energy (ATP), carbon dioxide, and water. The carbon dioxide is transported back to the lungs and expelled.
8. What is the difference between aerobic and anaerobic respiration?
| Feature | Aerobic Respiration | Anaerobic Respiration |
|---|---|---|
| Oxygen Requirement | Requires oxygen | Occurs without oxygen |
| Location in Cells | Takes place in mitochondria | Occurs in the cytoplasm |
| Energy Production | Produces high energy (38 ATP) | Produces less energy (2 ATP) |
| End Products | Carbon dioxide and water | Lactic acid (in animals) or alcohol and CO₂ (in yeast) |
| Example | Humans during normal breathing | Muscle cells during heavy exercise, yeast fermentation |
9. How do plants perform photosynthesis?
Plants perform photosynthesis using chlorophyll in their leaves to capture sunlight and convert carbon dioxide and water into glucose and oxygen. This process occurs in the chloroplasts and follows the equation:
6CO₂ + 6H₂O + sunlight → C₆H₁₂O₆ + 6O₂.
The glucose produced provides energy for the plant, while oxygen is released into the atmosphere
10. What is the role of stomata in photosynthesis?
Stomata are small pores on the leaf surface that are important in photosynthesis for gas exchange. They take in carbon dioxide (CO₂) from the atmosphere, which is utilized to synthesize glucose, and emit oxygen (O₂) as a waste product. Stomata also assist in transpiration, which regulates the water balance in plants.
