NEET BIOLOGY

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: -Light work Their roots take up water and minerals from the ground and their leaves absorb a gas called carbon dioxide (CO2) from the air. They convert these ingredients into food by using energy from sunlight. This process is called photosynthesis, which means ‘making out of light’.

Detailed explanation-3: -All leaves change sunlight into energy through photosynthesis. The leaves are the primary food-making part of the plant. Leaves absorb carbon dioxide from the air, combine it with water that comes through the roots of the plants to make food (a sugar molecule known as glucose), and release oxygen into the air.

Detailed explanation-4: -Answer: The main function of leaf is photosynthesis. It produces food for the plant. It has a photosynthetic pigment chlorophyll which converts solar energy into chemical energy. The leaf is also involved in the transpiration process.
