(i) in the shade
(ii) in dim light
(iii) under the fan

4. Why is transport of materials necessary in a plant or in an animal? Explain.
Transport of materials is necessary in both plants and animals as every cell needs regular supply of nutrients and oxygen for releasing energy through respiration.
The food that we eat is broken down into smaller components to be absorbed by cells. The oxygen we inhale also has to be transported to all the cells of the body. Our body also requires constant removal of waste materials such as carbon dioxide.
For the transport of all these materials (nutrients, oxygen and waste products) our body has a specialised transport system.
Similarly, in plants, the transport of water and food is accomplished with help of vascular tissues (xylem and the phloem).
5. What will happen if there are no platelets in the blood?
If there are no platelets, then blood will not clot as platelets release blood clotting factor at the site of injury and stops further bleeding.
6. What are stomata? Give two functions of stomata.
Tiny pores present on the leaf surface are known as stomata.
Functions of stomata
- Helps in exchange of gases
- Evaporation of water through leaves occurs due to stomata.
7. Does transpiration serve any useful function in the plants? Explain.
Transpiration serves the following functions in plants
- It helps in lowering temperature of plants, thus preventing heat injury of plants.
- Helps in transpiration pull, which helps in raining water in higher plants.
- It also causes loss of water absorbed by plants.
8. What are the components of blood?
Red blood cells, white blood cells, platelets and plasma.
9. Why is blood needed by all the parts of a body?
Blood is a significant part of transport system in our body, and we need blood for the following reasons:
- For the transport of oxygen to all parts of our body
- To expel out carbon dioxide from our body
- To transmit heat thus helping in the regulation of body temperature.
- It is required to fight out infections and diseases.
10. What makes the blood look red?
The presence of a red pigment called haemoglobin in red blood cells (RBC) makes the blood appear red.
11. Describe the function of the heart.
The heart is an organ which beats continuously to act as a pump for the transport of blood, which carries other substances with it. The heart has four chambers. The two upper chambers are called the atria (singular: atrium), and the two lower chambers are called the ventricles. The partition between the chambers helps to avoid mixing up of blood-rich in oxygen with the blood-rich in carbon dioxide. Blood flow from the heart to the lungs and back to the heart from where it is pumped to the rest of the body.
12. Why is it necessary to excrete waste products?
When our cells perform their functions, certain waste products are released. These are toxic and hence need to be removed from the body.
13. Draw a diagram of the human excretory system and label the various parts.
