The following are steps involved in abscisic acid's (ABA) role in stomata closure. Arrange them in the correct order of events. a. The resulting voltage change across the guard cell plasma membranes opens gated transport proteins that allow potassium ions to exit the cells
b. ABA binding to its receptor on a guard cell membrane causes the release of nitric oxide (NO). The NO activates calcium transport proteins and an influx of calcium occurs. c. Water follows the solutes by osmosis. d. The guard cells lose turgor and collapse against one another, closing the stoma. e. Calcium influx activates transport proteins that pump negatively charged malate and chloride ions out of the cells. Thus, the overall charge of cytoplasm increases, and the overall charge of extracellular fluid decreases.
