Explanation:

Transpiration is the process of water movement through a plant and its evaporation from aerial parts, such as leaves, stems and flowers. Water is necessary for plants but only a small amount of water taken up by the roots is used for growth and metabolism.

Answer 2

Loss of water through the pores present in leaves called stomata in the form of vapours is called transpiration. The stomata are the small pores present in the leaves. Transpiration helps the plants to take nutrients from soil. It also keeps the plant cool in hot weather conditions.

Role of transpiration in plants is as follows:

1. Creates transportational pull for transport of water in plants.
2. Provides water for photosynthesis.
3. Helps in the uptake of minerals from soil to upper parts of plant.
4. Cools the surface of the leaves (due to the evaporation of water).
5. Keeps the cells turgid; hence, maintains their shape.
