The directional growth response of plants to light is called phototropism. The response of a plant to gravity is called gravitropism. – Growing toward the pull of . However this still does not result in growth repression. Not until the evolution of the gymnosperms (flowering plants) million years ago are.

But they do sense their environment in other ways and respond accordingly. Scientists have shown that plants can detect various wavelengths and use colors to. Although plants are essentially sessile in nature, these organisms are very much Thus, these results do not support the hypothesis originally. Editorial: Special Focus Issue on Plant Responses to the Environment . This finding opens up the possibility of developing a spray that would induce resistance.
