Detailed explanation-1: -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-2: -This evolutionary innovation is so central to plant identity that nearly all land plants use the same pores-called stomata-to take in carbon dioxide and release oxygen. Stomata are tiny, microscopic and critical for photosynthesis. Thousands of them dot on the surface of the plants.

Detailed explanation-3: -These tiny pores present in the leaves are known as stomata. They help in the exchange of gases and also give out water vapour through transpiration.
