Potassium

Vedclass · Answer

(C) The opening and closing of stomata are primarily regulated by the movement of $Potassium$ $(K^+)$ 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 stomatal pore.Conversely,the efflux of $K^+$ ions leads to a decrease in turgor pressure,resulting in the closing of the stomata.

$Potassium$ ions play an important role in the opening and closing of stomata.
