Question

Write the name of a hormone that plays a major role in (i) falling of leaves (ii) rapid cell division. 

Hint:

Abscisic acid helps in maintaining plant water balance, while cytokinins are key regulators in stimulating plant cell division.

Answer 1

- (i) The hormone that plays a major role in F₂falling of leavesF₂ is F₂Abscisic acid (ABA)F₂. ABA promotes leaf abscission, particularly under stress conditions such as drought.
- (ii) The hormone that plays a major role in F₂rapid cell divisionF₂ is F₂CytokininsF₂. Cytokinins promote cell division and are often found in areas of active growth.
