Mention the major role of leaves in plants.
Leaves are thin, flattened, chlorophyll-bearing, photosynthetic organs of a plant.
The main function of the leaf is to manufacture food by the process called photosynthesis. This process takes place in the presence of sunlight and chlorophyll.
The leaf also helps in gaseous exchange and transpiration. Transpiration is an evaporative loss of water through the tiny pores called stomata.
