BIOMOLECULES AND ENZYMES

Detailed explanation-1: -Gibberellins stimulate germination of seeds. Gibberellins break the stored food by stimulating the production of enzymes during germination and end seed dormancy.

Detailed explanation-2: -GA stimulates the seed germination whereas, ABA is involved in the establishment and maintenance of dormancy. GA exerts its influence in two manners, first by increasing the growth potential of embryo and second by inducing hydrolytic enzymes.

Detailed explanation-3: -Auxin and cytokinin are critical growth hormones in plant development and are naturally present within the plant at variable concentrations throughout the season.

Detailed explanation-4: -The action mechanism is gibberellins induce the production of hydrolyzing enzymes. When these hydrolyzing enzymes in the endosperm are produced, they stimulate the production of digestive enzymes like proteases, amylase, and lipase which help to mobilize stored nutrients. Thus inducing the seed germination.
