Question

How does gibberellin accelerate seed germination?

• A. By producing ethylene
• B. By the production of enzymes which break down the stored food
• C. By absorbing water resulting in the swelling of seeds
• D. By producing abscisic acid

Answer 1

The correct option is B

By the production of enzymes which break down the stored food

Gibberellin breaks up stored food in the seeds by stimulating the production of enzymes. These enzymes help in the regulation of various developmental processes, including stem elongation, seed germination, dormancy, flowering, flower development and leaf and fruit senescence.
