During the day, what critical role do stomata play in the process of photosynthesis within plant leaves?
During the day, what critical role do stomata play in the process of photosynthesis within plant leaves?
- They facilitate the intake of carbon dioxide and the release of oxygen. (correct)
- They shield the plant from excessive sunlight exposure.
- They offer structural fortification against external physical harm.
- They regulate the distribution of water throughout the leaf tissue.
