Plant hormones affect how plants grow. Unlike animal hormones, plant hormones are organic molecules. They aid in plant growth and survival. Cellular events like division and cell morphology are driven by hormone levels. In plants, meristematic tissue is composed of cells that are actively growing. This is where one is expected to find a relatively large concentration of plant hormones. Also, one will find higher hormone levels in root tip.s 

Auxin speeds up growth on one side of the plant. The flowers lean toward the sunlight. 
Cytokinin stimulates the growth of roots and is added to the tips of cuttings before planting to increase the likelihood of them rooting.


Auxin is involved in the elongation of stems.
Cytokinins stimulate cell division.
Gibberellins control stem elongation.
Ethylene controls leaves and flower abscision.
Abscisic acid suppresses growth of budsand promotes leaf senescence.
