Detailed explanation-1: -Stomata are pores in the leaf that allow gas exchange. Each stoma is guarded by guard cells. When these guard cells open during photosynthesis, carbon dioxide enters the leaves and water vapour and oxygen goes out of the leaves. Stomata are present usually on the underside of the leaves.

Detailed explanation-2: -Stomata are tiny pores present on the surface of the leaves of plants. These pores are surrounded by guard cells. The carbon dioxide from the air is taken through these tiny pores to carry out the process called photosynthesis.

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.
