    Gibberelins are gibberelic acids! They mediate plant responses to light.

    your better of doing some research: u might find more detailed info
    I think gibberellin - aids the germination of the seed: (when seed is in contact with water- embryo secretes the plant hormone gibberellin-- then a series of enzyme reactions occur (digests starch to maltose) so the embryo can take in. Also it is involved in stem elongation (if the plant has the gene that codes for the active form of gibberellin that it will grow long .
