Heya !

Q : What are plant hormones ?

Ans :

Plant hormones, also known as phytohormones are chemicals that regulate plant growth. The term, Phytohormone was coined by Kenneth Vivian Thimann, in 1948. In plants, these are produced by cells in one area of the plant, such as leaves, stems or roots and then transported to a different area of the plant in order for them to have a response.

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.
