Explanation:
Detailed explanation-1: -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.
Detailed explanation-2: -The tiny openings are called the stomata.
Detailed explanation-3: -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.
