Question

What is a leaf and what role does it play in the life of a plant?

Answer 1

The leaf is a green, flat, thin, lateral structure borne on the stem. The green colour of leaf is due to the presence of chlorophyll that helps plants to synthesise their food. Hence, leaf prepares food for all the other parts of the plant. Leaves also maintain the temperature of a plant by loosing water in the form of vapours by the process of transpiration and they also help in respiration and gaseous exchange for photosynthesis through stomata.
