Which one of the following plant hormones is not correctly matched with its function?
Options
- AAbscisic acid – Stomatal closure
- BGibberellic acid – leaf fall
- CCytokinin – Cell division
- DIAA – Apical dominance
Correct answer
B. Gibberellic acid – leaf fall
Step-by-step solution
ABA commonly called as stress hormone causes closure of stomata. Cytokinin is important in promoting cell division, and auxin promotes apical dominance by inhibiting the growth of lateral bud. Gibberellin is a growth promoting hormone it delays the process of senescence and inhibits leaf fall.
