Detailed explanation-1: -Stomata help in exchange of gases i.e. uptake of carbon dioxide and release of oxygen. Stomata helps in the transpiration i.e. the loss of water from the surface of leaves in the form of water vapour.

Detailed explanation-2: -Stomata facilitate not only the uptake of CO2 but also the exchange of all gases between the aerial parts of the plant and the atmosphere. Water vapour and oxygen molecules exit the leaf through the same path as CO2 enters, but usually in the opposite direction (Figure

Detailed explanation-3: -Leaves of plants have tiny pores called stomata, which is used for the exchange of gases. The oxygen, taken in through stomata is used by the cells in the leaves to break down glucose into carbon dioxide and water.

Detailed explanation-4: -Small pores present on the surface of leaves which help in exchange of gases are called stomata.

Detailed explanation-5: -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.
