Question

How does the stomata affect the Light Reaction (2 things)?

Answer 1

CO2 used during photosynthesis first must pass through stomata into internal spaces within the leaf. It then diffuses into mesophyll cells where it becomes available for photosynthesis. When the stomata close, CO2 levels drop rapidly within the leaf, inhibiting the light-independent reactions.
