Detailed explanation-1: -The epidermis aids in the regulation of gas exchange. It contains stomata, which are openings through which the exchange of gases takes place. Two guard cells surround each stoma, regulating its opening and closing.

Detailed explanation-2: -Gas exchange occurs in plants through tiny pores called stomata, which are found on the leaves. Carbon dioxide enters the plant through the stomata, and oxygen is released.

Detailed explanation-3: -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.
