Question

Quizplus · Accepted Answer

All of these factors influence the opening and closing of the stomata.

The rate of photosynthesis affects the production of sugar, which can lead to changes in the osmotic pressure of guard cells, ultimately influencing the stomata's opening and closing. Water availability is critical to stomatal function, as it allows the guard cells to swell and change shape. The concentration of carbon dioxide in the leaf affects the rate of photosynthesis, which, as previously described, impacts the stomata's function. Finally, light availability influences the rate of photosynthesis and plant water use, both of which can affect stomatal function.
