Detailed explanation-1: -The main function of a leaf is to produce food for the plant by photosynthesis. Chlorophyll, the substance that gives plants their characteristic green colour, absorbs light energy. The internal structure of the leaf is protected by the leaf epidermis, which is continuous with the stem epidermis.
Detailed explanation-2: -Leaf prepares food for plants by the process of photosynthesis. Leaf has abundant stomata for gaseous exchange and performs the function of respiration. The leaf is the main site of water loss through the process of transpiration.
Detailed explanation-3: -(i) Sunlight, carbon dioxide, chlorophyll and water are necessary for photosynthesis. (ii) Oxygen is absorbed from the atmosphere during the process of photosynthesis. (iii) Leaves carry out photosynthesis.
