Q.7 Does transpiration serve any useful function in the plants? Explain.

Transpiration is the evaporation of water from plants.

Transpiration serves the following functions in plants:

(1) The water evaporates through the stomata present on the surface of the leaves. It helps in the distribution of water throughout the plant body.

(2) It also helps in maintaining the temperature in the plant thus preventing heat injury of plants.

(3) Transpiration creates the transpiration pull, which is responsible for the rise of water to great heights in tall plants and other trees.
