Vedclass · Answer

(A) The opening and closing of stomata are regulated by the turgor pressure of guard cells.According to the $K^+$ ion pump theory (active potassium transport theory),the accumulation of $K^+$ ions in the guard cells leads to a decrease in water potential.This causes water to enter the guard cells from adjacent subsidiary cells via osmosis,making the guard cells turgid and causing the stomata to open.Conversely,the efflux of $K^+$ ions leads to the loss of water,resulting in flaccid guard cells and the closing of stomata.

The opening and closing of stomata takes place as a result of active transport of . . . . . . ions in guard cells.
