What Are Examples of Plant Tropisms? A tropism is the manner in which a plant responds to an environmental stimulus, including light (phototropism), gravity (gravitropism) or touch (thigmotropism). Plants respond positively to some stimuli by moving toward them, and negatively to other stimuli by moving away from them.

tropism Driesch has found that a tropism underlies the arrangement of the skeleton in the pluteus larvae of the sea-urchin. As a type of human behavior it may be explained, like the attraction of the flame for the moth, as a sort of tropism. This may be a tropism (stereotropism) or it may be a mere surface tension phenomenon.
