Difference between phototropic movements and nastic movements |
| Answer» \tTropic and nastic movements are influenced by environmental cues. Tropic movements are found virtually in all plants but nastic movements are mostly found in specialized plants and organs.\tIn tropic movements, there is directional growth of a plant, or part of a plant, in response to an external stimulus such as gravity or light. So the direction of the stimulus controls the orientation of growth. The direction of a nastic movement is independent of where the signal comes from. It is only the quality, and not the direction, of the stimulus that triggers a response.\tIn tropism, the effect is more or less permanent. Most nastic movements are temporary and reversible.\tNastic movements are more specialized in function and distribution than tropic movements. | |
