Detailed explanation-1: -Stomata is one such part that is involved in the exchange of gases by plants. There are thousands of stomata located on the lower surface of the leaves. Stomata are kind of tiny openings present on the epidermis of the leaves. Stomata can be seen under a light microscope.

Detailed explanation-2: -The exchange of oxygen and carbon dioxide in the leaf (as well as the loss of water vapor in transpiration) occurs through pores called stomata (singular = stoma). Normally stomata open when the light strikes the leaf in the morning and close during the night.

Detailed explanation-3: -Stomata are the centres of exchange of gases in plants. The gases diffuse into the intercellular spaces of the leaf through these pores, which are normally on the underside of the leaf.

Detailed explanation-4: -The leaves exchange gases through pores called Stomata. Stomata are the small openings present on the inner surface of the leaves. Stomata can be opened and closed. During the night when no photosynthesis takes place, the plant breathes in oxygen and breathe out carbon dioxide through stomata.
