Question

Quizplus · Accepted Answer

Stomata are small openings found on the underside of leaves that allow for gas exchange, specifically the intake of carbon dioxide for photosynthesis and the release of oxygen and water vapor. They are not located in the upper epidermis, and are surrounded by two guard cells, not four. Stomata are not involved in primary or secondary growth.
