What happens to ordinary plants (not C4 or CAM) when stomata close? Photosynthesis stops due to a lack of carbon dioxide. Enzymes change carbon dioxide to a four-carbon sugar. Photosynthesis stops due to a lack of water. Enzymes change carbon dioxide to glucose.

Photosynthesis stops due to lack of carbon dioxide

Explanation:

Plants take CO2 from the stomata. It can take water from xylem but it takes CO2 only through stomata. However, the other 2 options don;t happen.
