Vedclass · Answer

(B) The opening and closing of stomata are primarily regulated by the movement of $K^+$ (potassium) ions into and out of the guard cells.When $K^+$ ions enter the guard cells,the osmotic pressure increases,causing water to enter the cells via osmosis.This increases the turgor pressure of the guard cells,leading to the opening of the stomata.Conversely,the efflux of $K^+$ ions leads to the loss of water and the closing of the stomata.
