Seeds containstored foodin the cotyledons to provide energy and materials for growth. This is usually in the form ofstarch– a large,insolublemolecule (long chain of glucose), that keeps the food immobile. The starch needs to be changed into asolublemolecule (sugar) with help ofenzymesforthe seeds to make use of.
Things to remember:
In the presence of H2O, Gibberellin or gibberellic acid (GA) stimulates the production of amylase.
Amylase breaks down starch to maltose, allowing for the formation of ATP (via glucose).
The energyproduced in the embryo is used to facilitate germination.
The glucose produced may also be used to synthesis cellulose - for cell wall formation.

hey love your blog ...good job! ...do u use adsense?
ReplyDeleteGreat information
ReplyDeletewhat are your sources ?
ReplyDeletehello
ReplyDeletei love seed germinastion.<3
am i the only one who just can't understand bio at all?
ReplyDeletei need info which enzyme involved in seed germination
ReplyDeletelike a-amylase, b-amylase , catalyses and lipase
This is really helpful. Thank you very much.
ReplyDeleteNo comment what i need to know is type of enzymes
ReplyDeleteGreat job
