Question

Which of the following is not a function of abscisic acid?

• A. It helps the seeds to survive under extreme unfavourable conditions
• B. It helps in the storage of seed for agricultural purpose.
• C. It induces elongation of stem
• D. It induces the closure of stomata

Answer 1

The correct option is C It induces elongation of stem

Abscisic acid is a plant growth inhibitor. It induces dormancy in seeds to survive unfavourable conditions i.e., very high or very low temperature. It helps in the storage of seed for later use. It also helps in the closure of stomata and prevents water loss through it.

Auxins and gibberellins are plant growth promoters that help in the elongation of stem.
