Answer:
Explanation:
(a)Apical bud inhibits the growth of lateral buds by releasing auxins. When the apical bud is removed, the lateral buds sprout. This produces dense bushy growth. The phenomenon is widely used in tea plucking and hedge making.
(b)Abscisic acid stimulates the closure of stomata in the epidermis and increases the tolerance of plants to various kinds of stresses. So, it is called the stress hormone.
