Solution and Explanation
Concept:
Plant hormones (phytohormones) regulate growth, development, and responses to environmental stimuli.
Answers:
- (i) Promote cell division → Cytokinins
- (ii) Inhibition of growth → Abscisic acid (ABA)
- (iii) Detection of light → Auxins
- (iv) Wilting of leaves → Abscisic acid (ABA)
- Cytokinins stimulate cell division in plants.
- Abscisic acid acts as a growth inhibitor and induces dormancy and wilting.
- Auxins help plants respond to light (phototropism).
- ABA causes stomatal closure leading to wilting under stress conditions.
