Detailed explanation-1: -The leaves of the plants have tiny pores called stomata for the exchange of oxygen and carbon dioxide.

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.

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: -Carbon dioxide and oxygen cannot pass through the cuticle, but move in and out of leaves through openings called stomata (stoma = “hole"). Guard cells control the opening and closing of stomata. When stomata are open to allow gases to cross the leaf surface, the plant loses water vapor to the atmosphere.

Detailed explanation-5: -Stomata and Gas Exchange Each stoma is surrounded by two guard cells, which can open and close depending on environmental conditions. When moisture is plentiful, the guard cells swell with water, forcing the opening of the stoma open and allowing gas exchange to occur.
