The process of seed germination is stimulated due to the synthesis of hydrolytic enzymes. Which hormone is responsible for this process?
Options
- AAbscissic Acid.
- BCytokinin.
- CEthylene.
- DGibberellin.
Correct answer
D. Gibberellin.
Step-by-step solution
During seed germination, the embryo releases gibberellins, which diffuse into the aleurone layer of the seed.
Gibberellins stimulate the synthesis of hydrolytic enzymes such as -amylase, proteases, and lipases in the aleurone layer.
These hydrolytic enzymes break down the stored food reserves (starch, proteins, and lipids) in the endosperm into simpler, soluble forms.
The mobilized nutrients are then transported to the growing embryo, providing the necessary energy and materials for its growth and development, thereby promoting seed germination.
