Vedclass · Answer

(D) According to the proton transport theory proposed by Levitt $(1974)$,the opening of stomata is driven by the active uptake of potassium ions $(K^+)$ into the guard cells.To maintain electrical neutrality,the uptake of $K^+$ ions is balanced by the uptake of chloride ions $(Cl^-)$.Additionally,starch is converted into malic acid,which dissociates into hydrogen ions $(H^+)$ and malate ions.The accumulation of these solutes (malate,$K^+$,and $Cl^-$) in the vacuoles decreases the water potential of the guard cells,leading to the influx of water via osmosis,which causes the stomata to open.

Which of the following get accumulated in the vacuoles of guard cells during stomatal opening?
