In stomatal lineage cells, we showed that members of PRAF proteins interact with BASL and, when highly expressed in the stomatal lineage cells, become polarized in a BASL-dependent manner (Fig. 3d, e). WebStage-3: The neurotransmitter causes sodium ion channels to open, hence the neural membrane becomes polarized, and the impulse carried through the neural cell membrane becomes depolarized. If the potassium ions channel opens, the neural cell membrane becomes hyperpolarized and leads to inhibition of nerve impulse. china has won ai battle with u.sWebWhat is polarization of cell in physics?
