Despite not having sense organs plants can also sense things and respond to them. Plants respond to things like light, gravity, touch, water etc. These are environmental stimuli for a plant. Plants coordinate their behaviour by using their hormones and respond to the environmental changes. This they do by affecting the growth of a plant.

Therefore, pants use only hormones to coordinate their behaviour. They respond to the stimuli very slowly because they have no nervous system. Plant hormones are called phytohormones.

Dormancy: The inactive condition of a part of a plant in which metabolism almost stops is called dormancy. For example, seed, bud etc.
