Correct Answer: B
Solution :The hydrolysis of stored starch, proteins and lipids is an important event that takes place early during seed germination, In germinating seeds of barley and other cereal crops, the embryo secretes gibberellins just after imbibition. This hormone diffuses through the endosperm to a surrounding tissue called the aleurone layer, which lies underneath the seed coat. The gibberellins trigger a cascade of events in the aleurone layer, causing it to synthesise and secrete enzymes that digest proteins and starch stored in the endosperm, releasing monomers (nutrients) that can be used by the developing embryo.
