NEET BIOLOGY

Detailed explanation-1: -On the underside of leaves and elsewhere, depending on the plant, are tiny openings called stomata-thousands of them per leaf with variations by plant species. Like little castle gates, pairs of cells on the sides of the stomatal pore-known as guard cells-open their central pore to take in the carbon dioxide.

Detailed explanation-2: -Stomata resemble doughnuts-a circular pore with a hole in the middle for gas to enter or leave the plant. The pore consists of two cells-each known as a guard cell.

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, as mentioned above, are the structures through which gas exchange occurs in leaves. Each stoma is surrounded by two guard cells, which can open and close depending on environmental conditions.
