Answer 1

Answer:

Cytokinins delay aging in leaves and flowers. Gibberellins elongate stem internodes in lettuce to elevate flowers and seeds for pollination and dispersal. Gibberellins stimulate breakdown of endosperm, growth of the embryo, and seed germination. Greenhouses use gibberellins to germinate dormant seeds.
