What are phytohormone mention any 3function

Hormones present in the plant are called as phytohormones. Phytohormones help in coordinating growth, development and response of the plant to the environment. Hormones are the chemical compounds released by stimulated cells. Hormones diffuse all around the cell.
Different hormones secreted by the plant are auxins, gibberellins, cytokinins, abscisic acid.
*Auxins are the hormones synthesised at the tip of the stem. These help the plant in growth by cell elongation.
*Gibberellins are hormones that help in the growth of the stem, seed germination, bolting, and flowering.
*Cytokinins are hormones present in the areas of rapid cell division, such as fruits and seeds. They also promote the opening of the stomata.
*Ethylene is the hormone which brings in the ripening of fruits.
*Abscisic acid is a hormone that inhibits the growth in various parts. It is also responsible for the closure of stomata.
