Why is abscisic acid called a growth-inhibiting hormone?
Answer and explanation
Correct answer: It can slow down or stop plant growth
Plant hormones may promote growth or inhibit it according to the hormone and condition. Abscisic acid, or ABA, generally suppresses growth, promotes dormancy, and helps plants respond to stress such as drought by reducing water loss through stomatal closure. Therefore, it is called a growth-inhibiting hormone. Stem elongation and increased cell division are associated with other hormones, while blood sugar is an animal-regulation concept. Option A is correct.
