Answer:

The main functions of a leaf of a plant are :-

1. Manufacture of food : Plants prepare their food in the presence of Sunlight and chlorophyll with the help of water , minerals and carbon dioxide . This plant food is a kind of simple sugar called glucose . This process of making food by green plants is called Photosynthesis.
2. Exchange of Gases : Plants breathe with the help of Leaves . Leaves have numerous tiny openings called stomata on their lower surface. The Exchange of Gases take place through this Stomata.
