Question

Quizplus · Accepted Answer

Regulators of stomatal opening and closing work by activating the proton pump in guard cells, which causes the movement of ions such as potassium and chloride. This ion movement leads to changes in osmotic pressure, causing the guard cells to either swell or shrink and thus inducing stomatal opening or closing. The proton pump in stomata and the sodium-potassium pump in guard cells and stomata are not directly involved in stomatal regulation.
