Chemical coordination occur in plants with the help of pytohormons or plant hormons secreted by plants.Auxin, cytokinin,gibberelline,abscisic acid are plant hormones.These hormones regulate yhe growth and development of the plants.They also regulates various metabolic activities in the plants.These hormones respond to the external stimuli like light,temperature etc.For example auxin is responsible for the growth of the plants and Cytokinin is responsible for the cell division.Similarly gibberellin is responsible for stem elongation,flowering, fruit ripening.Abscisic acid is responsible for the dormancy.
