Quick Summary

Traumatropism is a biological response where an organism, typically a plant, modifies its orientation due to wounding. This phenomenon is a type of tropism, which is the directional growth or movement of an organism in response to an external stimulus. While plants do not feel pain as animals do, they can respond to physical damage. Traumatropism specifically refers to the change in direction of growth, such as a plant root, after experiencing a wound. This is one of several tropisms, including responses to light (phototropism) and gravity (geotropism).123

…thigmotropism (response to mechanical stimulation), traumatotropism (response to wound lesion), and galvanotropism, or electrotropism (response to electric current). Most tropic movements are orthotropic; i.e., they are directed toward the source of the stimulus. Plagiotropic movements are oblique to the direction of stimulus. Diatropic movements are at right angles to the…
