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: -What is the role of leaves in photosynthesis? The broad surface area of leaves allows for enhanced absorption of sunlight. Moreover, numerous pores, called stomata, allow easy gaseous exchange. Therefore, leaves act as the primary location for photosynthesis.

Detailed explanation-4: -Leaves not only perform the function of transpiration but also perform the functions of photosynthesis and gaseous exchange through tiny pores in them known as stomata.
