Detailed explanation-1: -Leaves of green plants contain openings known as stomates, which are opened and closed by specialized cells allowing for gas exchange between the leaf and the outside environment.
Detailed explanation-2: -Stomata (noun, “STO-mah-tah”, singular “stoma”) These are the small pores in plant stems or leaves that allow carbon dioxide in and oxygen and water vapor out. Each tiny hole is surrounded by a pair of cells called guard cells. These cells control whether a stoma is open or closed.
Detailed explanation-3: -stomate, also called stoma, plural stomata or stomas, any of the microscopic openings or pores in the epidermis of leaves and young stems. Stomata are generally more numerous on the underside of leaves.
Detailed explanation-4: -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.
