Active $K^+$ transport theory

Vedclass · Answer

(D) The active $K^+$ transport theory,also known as the proton-potassium pump hypothesis,is the most widely accepted modern explanation for stomatal movement.During the day,light triggers the active transport of $K^+$ ions into the guard cells,which increases their osmotic pressure and turgidity,leading to the opening of the stomata.Conversely,during the night,$K^+$ ions move out of the guard cells into the surrounding subsidiary (epidermal) cells.This efflux of ions causes the guard cells to lose water,become flaccid,and result in the closure of the stomata.

Which of the following theories provides the latest explanation for the closure of stomata?
