What are plant hormones?
Answers
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.
Explanation
Plant hormones (also known as phytohormones) are signal molecules, produced within plants, that occur in extremely low concentrations. Plant hormones control all aspects of plant growth and development, from embryogenesis,[1] the regulation of organ size, pathogen defense,[2][3] stress tolerance[4][5] and through to reproductive development.[6] Unlike in animals (in which hormone production is restricted to specialized glands) each plant cell is capable of producing hormones.[7][8] Went and Thimann coined the term "phytohormone" and used it in the title of their 1937 book.[9]
Lack of the plant hormone auxin can cause abnormal growth (right)
Phytohormones occur across the plant kingdom, and even in algae, where they have similar functions to those seen in higher plants.[10] Some phytohormones also occur in microorganisms, such as unicellular fungi and bacteria, however in these cases they do not play a hormonal role and can better be regarded as secondary metabolites.[11]
