Which plant physiological process is stimulated by ABA?

Options

  1. ALeaf expansion
  2. BRoot elongation
  3. CClosure of stomata
  4. DFruit development

Correct answer

C. Closure of stomata

Step-by-step solution

ABA stimulates the closure of stomata in the epidermis and increases the tolerance of plants to various kinds of stresses. Therefore, it is also called the stress hormone. ABA plays an important role in seed development, maturation and dormancy. By inducing dormancy, ABA helps seeds to withstand desiccation and other factors unfavourable for growth.
