GinnyAnswer

Final answer:

High sugar concentration causes stomatal closure to conserve water in plants.


Explanation:

The factor that opposes the opening of stomata is high sugar concentration. When there is a high sugar concentration, the osmotic potential of the guard cells decreases, leading to water moving out of the cells and causing stomatal closure. This physiological response helps plants conserve water during times of stress.
