Vedclass · Answer

(C) The correct answer is $C$. During the process of stomatal opening (photoactive),the following events occur:$1$. The $pH$ of guard cells increases due to the dissociation of malic acid into malate ions and $H^+$ ions.$2$. Starch in the guard cells undergoes hydrolysis to form phosphoenolpyruvate $(PEP)$.$3$. Malic acid dissociates into malate ions and $H^+$ ions.$4$. As a result of these processes,the osmotic potential of the guard cells decreases,causing water to enter the guard cells from the subsidiary cells via osmosis. This increases the turgor pressure $(TP)$ of the guard cells,not the subsidiary cells,leading to the opening of the stomata.Therefore,an increase in the $TP$ of subsidiary cells does not occur; instead,their $TP$ decreases as they lose water to the guard cells.
