Answer:
Phytohormones or plant hormones, are naturally occurring small organic molecules or substances which influence physiological processes in plants at very low concentrations.
The major classes of traditionally accepted plant growth regulators are auxins, cytokinins, gibberellins, abscisic acid, ethylene, and the brassinosteroids, with the first two being the most well recognized and utilized in commercial applications.
Plant hormones as signal molecules regulate cellular processes in targeted cells locally and when moved to other locations of the plant. They also determine the formation of the root, stem, leaf, and flower and facilitate the shedding of leaves and the development and ripening of fruits.
