14.1: Tropisms - Biology LibreTexts

WebA tropism is a directional growth response to a stimulus, for example to light, water, or gravity. These responses can be the result of cells growing longer, or elongating, but this is not always the case. Tropisms may actually cause a change in direction of growth by inhibiting elongation of cells. WebConsequently, the single most important outcome of the experiments in space was that they demonstrated that the growth of mushroom stems in a vertical orientation on Earth is a response to the gravity vector; it really is a gravitropism.
