Tropism explained
In biology, a tropism is a phenomenon indicating growth or turning movement of an organism, usually a plant, in response to an environmental stimulus. In tropisms, this response is dependent on the direction of the stimulus (as opposed to nastic movements which are non-directional responses). Tropisms are usually named for the stimulus involved; for example, a phototropism is a re… WebGeotropism is the influence of gravity on plant growth or movement. Simply put, this means that roots grow down and stems grow up. Geotropism comes from two words, “geo” which means earth or ground and “tropism” which means a plant movement triggered by a stimulus. In this case, the stimulus is gravity. Upward growth of plant parts ...
