Question

Plant responses to abiotic stress - Stomatal control

Accepted Answer

open/close stomata to cool/conserve water, leaf cells release ABA in response to abiotic stresses, causing stomal closing, also roots release ABA when low WP in soil (transpiration threatened) towards leaves (where it binds to receptors on guard cells to dec WP/turgor of cells, so stoma closes and less water lost
