Detailed explanation-1: -During photosynthesis, leaves take in atmospheric CO2 and release O2 through stomata, microscopic pore structures in the leaf epidermis (singular = stoma). A pair of guard cells surrounds each stoma, and these cells control the opening and closing of the stomatal pore between them.

Detailed explanation-2: -Stomata, regulated by guard cells, allow gases to pass in and out of the leaf. We may not be able to see them with the naked eye, but the leaves of plants contain tons of tiny holes, or pores, called stomata (sing. stoma).

Detailed explanation-3: -The structure of the stomata comprises a kidney-shaped epidermal cell along with an opening in the center called a pore. The stomata are bordered by a pair of specialized parenchyma cells which are the guard cells. These are responsible for regulating the size of its opening, thereby saving the plant from water loss.

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.

Detailed explanation-5: -Plants ‘breathe’ too, but they do it through tiny openings in leaves called stomata (singular: stoma). Stomata open and close to allow the intake of carbon dioxide and the release of oxygen.
