Plant hormones
the control and coordination in plant is done by hormones called plant hormones are phytohormones.
There are 4 types of plant hormones:-
1. Auxin - it is produced at shoot tip in presence of light. it promotes cell division and elongation.
2. Gibberellin - it help in stem growth. it result in increase the size of fruits and flowers.
3. cytokinin - it promotes cell growth. they delaying aging.
4. abscisic acid - it inhibits growth.

GROWTH PROMOTERS :
1.When growing plants detect light, a hormone called auxin, synthesised at the shoot tip, helps the cells to grow longer. When light is coming from one side of the plant, auxin diffuses towards the shady side of the shoot.
This concentration of auxin stimulates the cells to grow longer on the side of the shoot which is away from light. Thus, the plant appears to bend towards light.
2.Another example of plant hormones are gibberellins which, like auxins, help in the growth of the stem.
3. Cytokinins promote cell division, and it is natural then that they are present in greater concentration in areas of rapid cell division, such as in fruits and seeds.
GROWTH INHIBITOR:
4. Abscisic acid is one example of a hormone which inhibits growth. Its effects include wilting of leaves.
