Question

Quizplus · Accepted Answer

Stomata are small pores on the leaves of plants that allow for gas exchange, specifically the entry of carbon dioxide and the exit of oxygen during photosynthesis. Mesophyll cells and chloroplasts are involved in the process of photosynthesis, but they do not actively permit CO₂ and O₂ to enter and exit the leaf. Thylakoids are located within chloroplasts and assist in the light-dependent reactions of photosynthesis, but they do not have a direct role in gas exchange.
