Vedclass · Answer

(D) Potassium $(K^+)$ ions play a crucial role in the movement of water into and out of guard cells. When $K^+$ ions enter the guard cells,the osmotic pressure increases,causing water to enter,which leads to the turgidity of the guard cells and the opening of the stomata. Conversely,when $K^+$ ions exit,the guard cells lose turgidity,leading to the closing of the stomata. Therefore,potassium is essential for the opening and closing of stomata.
