Answer: A tropism is a growth toward or away from a stimulus. Common stimuli that influence plant growth include light, gravity, water, and touch.


Plant tropisms differ from other stimulus generated movements, such as nastic movements, in that the direction of the response depends on the direction of the stimulus.
