Vedclass · Answer

(C) According to the $K^+$ ion pump theory (Levitt,$1974$),the opening and closing of stomata are regulated by the movement of potassium ions $(K^+)$ in and out of the guard cells.When stomata open,$K^+$ ions move from the surrounding subsidiary cells into the guard cells (influx).This influx of $K^+$ ions increases the solute concentration inside the guard cells,leading to a decrease in water potential.Consequently,water enters the guard cells from the surrounding cells via osmosis,causing them to become turgid and resulting in the opening of the stomatal pore.
