1)Plant hormones are the chemicals that regulate plant growth.They are also required in their metabolic activities and maintainig the functions of the plant body.
2)Hydro-tropism is the movement of a plant-body part or growth-response to the stimulus of water.
Chemo-tropism is the movement of a plant body part or growth response to the stimulus of chemicals.
3)Stimulus is the detectable change in the internal and external environment.It can be said as a reaction of our body (internal or external) when something happens to us.
