Question

Main task of stomata is to

• A. Intake of carbon dioxide and the release of oxygen
• B. Intake of water
• C. Release of carbon dioxide
• D. Release of sugars

Answer 1

The correct option is A Intake of carbon dioxide and the release of oxygen

Stomata is a pore, found on the underside of leaves, that facilitates gas exchange.
Carbon dioxide enters the plant through these openings by gaseous diffusion, which is used in photosynthesis . Oxygen produced as a by-product of photosynthesis diffuses out to the atmosphere through these same openings.
Also, water vapor diffuses through the stomata into the atmosphere in a process called transpiration.
