A tropism is a growth movement of a part of a plant in response to a directional stimulus. Tropisms can be towards the stimulus (known as positive tropisms) or away from the stimulus (known as negative tropisms) Plants responses include a variety of tropisms, including: Phototropism. Geotropism. Hydrotropism.
