Vedclass · Answer

(D) The opening and closing of stomata are regulated by the movement of $K^+$ ions in and out of the guard cells.When $K^+$ ions accumulate in 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,when $K^+$ ions move out of the guard cells,water follows,leading to a decrease in turgor pressure and the closure of the stomata.Therefore,the correct answer is $Potassium$ $(K^+)$.

The metal ion involved in the stomatal regulation is,or stomata will open if there is an accumulation of the following element in the guard cells:
