Gibberellic acid in this case is best described as a plant growth regulator or hormone that induces the expression of genes responsible for producing hydrolytic enzymes. These enzymes are crucial for breaking down stored starches in the grass seed's endosperm into simpler sugars, which are then used as a source of energy for the growing seedling. The action of gibberellic acid at the molecular level involves promoting the transcription of certain genes into messenger RNA (mRNA), the template for protein synthesis, which leads to the production of the hydrolytic enzymes necessary for germination and growth.
