Vedclass · Answer

(C) Abscisic acid $(ABA)$ acts as a stress hormone in plants. When plants experience water stress,$ABA$ is synthesized in the leaves. It inhibits the $H^+/K^+$ exchange mechanism in the guard cells and promotes the efflux of potassium ions $(K^+)$ and malate. This reduction in osmotically active solutes causes water to move out of the guard cells,making them flaccid. As a result,the stomatal pore closes to prevent further transpiration.
