Which of the following get accumulated in vacuoles of guard cells during stoamtal opening?
Open in App
Solution
The correct option is D Malate, K and Cl
Stomatal opening is controlled by turgor pressures. These pressures are maintained by K ions. These get accumulated in the vacuoles of the guard cells. Increase in K levels causes the change in water potential in the cell which forces the cell to take up water, swell and open.Cl and malate act as counter ions and help in the regulation of opening and closing the pore.Water, Ca, Mg, Na does not participate in this process.So the correct answer is 'Malate, K and Cl'.
