Class 7 Science Chapter 11 Question Answer:

Q3. Choose the correct option:

(a) In plants, water is transported through

(i) xylem

(ii) phloem

(iii) stomata

(iv) root hair

Answer: In plants, water is transported through the xylem.

So, the correct answer is (i) xylem.

Q3. Choose the correct option:

(b) Water absorption through roots can be increased by keeping the plants

(i) in the shade
(ii) in dim light
(iii) under the fan
(iv) covered with a polythene bag

Answer: Water absorption through roots can be increased by keeping the plants under the fan because the transpiration process is boosted.

Hence, the correct answer is (iii) under the fan.

Class 7 Science Chapter 11 NCERT Solutions:

Q4. Why is the transport of materials necessary in a plant or in an animal? Explain

Answer: Transport of materials is necessary for plants and animals because due to transportation the nutrients and oxygen are made available to all the parts of the body.

If the transport of necessary nutrients and oxygen does not take place in the body, the body will not be able to survive.

Class 7 Transportation in Animals and Plants NCERT Solutions:

Q5. What will happen if there are no platelets in the blood?

Answer: Blood platelets help to clot the blood. When there is some injury occurs blood starts flowing and if there are no platelets,

the blood will not be able to clot and keep on flowing. Therefore can cause death because of the huge loss of blood.

Transportation in Animals and Plants Class 7 Questions and Answers:

Q6. What are stomata? Give two functions of stomata.

Answer: There are small openings or pores on the lower surface of the leaves called stomata these opening are surrounded with guard cells.

The two functions of stomata are:

(i) Transpiration is possible through stomata, i.e., excess water loss from the plant.

(ii) Absorption of water from the roots, when there is the loss of water from the stomata creates an upward pull.

(iii) Exchange of gases.

Class 7 Science Ch 11 Question Answer:

Q7. Does transpiration serve any useful function in the plants? Explain

Answer: Transpiration helps in many ways:

(i) To enhance the absorption of water and dissolved minerals by the creation of a suction pull.

(ii) It helps in the loss of excess water from the plant.

(iii) Photosynthesis is possible because of the transportation of water and minerals to the leaves.

Class 7th Science Chapter 11 Solutions:

Q8. What are the components of blood?

Answer: There are four components of blood:

(i) Platelets: It helps in the formation of blood clots thus preventing the excessive bleeding from the wounds.

(ii) Plasma: They are present in the blood cells and also contains dissolved nutrients.

(iii) Red blood cells (RBC): They are the most abundant cells in the blood. RBC contains a red pigment called hemoglobin which carries oxygen and transports it to all the parts of the body.

(iv) White blood cells (WBC): They help the body to fight against the diseases by changing their shapes. Thus, they constitute the immune system of the body.

Chapter 11 Science Class 7th Question Answer:

Q9. Why is blood needed by all the parts of a body?

Answer: Blood is needed by all parts of the body because it is an important part of the transport system of our body and performs the following these important functions:

(i) Transports oxygen from the lungs to all the body cells.

(ii) Carries carbon-dioxide, waste products back to the lungs so that it can be exhaled easily.

(iii) Blood fights against diseases and infections.

Transportation in Animals and Plants NCERT Solutions:

Q10. What makes the blood look red?

Answer: Blood looks red because of the presence of haemoglobin, a red pigment in the red blood cells or RBC's that makes blood appear red in colour.

The haemoglobin carries oxygen and transports it to all the parts of the body.

Class 7th Science Chapter 11 Question Answers:

Q11. Describe the function of the heart.

Answer: The human heart is divided into four chambers where the upper two chambers are called right and left atrium and the lower chambers are called the right and left ventricles, therefore the functions of the heart are as follows:

(i) The right atrium receives carbon dioxide-rich blood from the body. Blood from the right atrium enters the right ventricle, which contracts and pumps the blood to the lungs.

(iii) Oxygen-rich blood from the lungs returns to the left atrium, then blood enters the left ventricle which contracts and pumps the blood to all parts of the body.

Hence basic function is to beat with rhythmic contraction and expansion throughout the life and transport the blood as a pump.

Q12. Why is it necessary to excrete waste products?

Answer: The waste produced by our cells are toxic and therefore need to be excreted out. The process of removal of waste products produced in the cells of living organisms is called excretion.

2. What are the function of blood vessel?

The blood is a red fluid that runs through our entire body, it does so through a special network called blood vessel

3. What are the topics covered in NCERT Class 7 chapter 11?

Here are the topics covered in NCERT Class 7 chapter 11

Circulatory System
Blood
Blood Vessels
Heart
Heartbeat
Excretion in Animals
Excretory System in Humans
Transport of Substances in Plants
Transport of Water and Minerals
Transpiration

4. What is transportation in animals and plants Class 7?

The definition of transport is a life process in which a substance is absorbed in one organ or part of an organism and then transported to other areas of that organism's body.

To reach every area of the plant, the food must be transported. The phloem, a type of vascular tissue, performs this function. Thus, in plants, xylem and phloem carry substances. The blood that circulates in the bodies of most animals carries nutrients and oxygen to various body cells.
