 The main function of abscisic acid in plants is to
(a) increase the length of cells
(b) promote cell division
(c) inhibit growth
(d) promote the growth of stem

Answers (1)

(c) inhibit growth

Explanation: Abscisic acid is the plant hormone. It is also called a stress hormone because it shows different responses to stress conditions. It leads to seed dormancy and ensures seed germination only when favourable conditions return. It also causes the closing of stomata when plants don’t get enough water. Hence, (c) is the correct option.
