Question

Explain the main functions of leaf.

Answer 1

Leaves are vital to the survival of plants. There are following two main functions of the leaf:

(i) Transpiration: The extra water comes out of the leaves in the form of vapor. This process is called transpiration.
(ii) Photosynthesis: The process by which leaves prepare their food from water and carbon dioxide, in the presence of sunlight and a green-colored substance, is called photosynthesis.
