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: -Leaves use chlorophyll to trap energy from the sun in a process called photosynthesis. The energy is used to combine water from the soil and carbon dioxide gas from the air to make sugar as food for the plant.

Detailed explanation-3: -Leaves provide food and air to help a plant stay healthy and grow. Through photosynthesis, leaves turn light energy into food. Through pores, or stomata, leaves “breathe” in carbon dioxide and “breathe” out oxygen.

Detailed explanation-4: -The leaves prepare food for the plants, using water and carbon dioxide in the presence of sunlight and chlorophyll. This process is called photosynthesis. The prepared food is in the form of glucose.

Detailed explanation-5: -Chlorophyll is a green colour pigment present in the leaves of the plants. It helps the plants to make their food by absorbing sunlight. Q. Plants make their own food using carbon dioxide and water in the presence of sunlight.
