Question

Gibberellins can facilitate seed germination because they can influence the

• A. synthesis of abscisic acid
• B. rate of cell division
• C. production of hydrolyzing enzymes
• D. absorption of water through the hard seed coat

Answer 1

The correct option is C

production of hydrolyzing enzymes

Gibberellins induce the production of hydrolysing enzymes in the endosperm of germinating seeds and help in breaking seed dormancy.

Abscisic acid inhibits seed germination. Cytokinin promotes cell division. Dormancy caused by hard and impermeable seed coats can be overcome by the action of soil microbes and also when they pass through the digestive system of animals.
