Answers

Answered by AKD777

Answer:

Plant hormones are signal molecules, produced within plants, that occur in extremely low concentrations. Plant hormones control all aspects of plant growth and development, from embryogenesis, the regulation of organ size, pathogen defense, stress tolerance and through to reproductive development.

Plant hormones, including auxin, cytokinins, abscisic acid (ABA), gibberellins, ethylene, jasmonates, brassinosteroids and strigolactones, are able to regulate different functions in plant at cellular and molecular levels.
