Which hormone is involved in the regulation of stomatal closure during water stress? (2023)

Step 1: Understand what stomata are. Stomata are tiny openings on the surface of leaves that allow gas exchange.
Step 2: Learn about water stress. Water stress occurs when plants do not have enough water.
Step 3: Know the role of hormones in plants. Hormones are chemicals that help regulate various functions in plants.
Step 4: Identify the hormone involved in water stress. The hormone abscisic acid (ABA) is produced when a plant experiences water stress.
Step 5: Understand how abscisic acid works. Abscisic acid signals the stomata to close, which helps reduce water loss from the plant.
Step 6: Conclude that abscisic acid is the hormone that regulates stomatal closure during water stress.
