NEET BIOLOGY

Detailed explanation-1: -Leaves are adapted for photosynthesis and gaseous exchange. They are adapted for photosynthesis by having a large surface area, and contain openings, called stomata to allow carbon dioxide into the leaf and oxygen out.

Detailed explanation-2: -The main functions of leaves are photosynthesis, exchange of gasses and transpiration.

Detailed explanation-3: -Stomata are the pores via which leaves exchange gases. During the night, when photosynthesis is not taking place, the plant uses stomata to take in oxygen and expel carbon dioxide. Stomata allow the plant to shed water in the form of vapour.
