WebThe mechanism of phototropism is as follows: Light of wavelength 450 nm illuminates the plant. The photoreceptor receives the light, reacts to … WebAnother commonly observed tropic responses is gravitropism, where a plant will grow so that it stays oriented relative to the source of gravity (the earth). Thus, if a plant is knocked down the shoot will grow faster on the lower side until the shoot is more-or-less standing up again. Tropic responses result from differential growth.
