WebPhototropism is most often observed in plants, but can also occur in other organisms such as fungi. The cellson the plant that are farthest from the light contain a hormone called auxinthat reacts when phototropism occurs. This causes the plant to have elongated cells on the furthest side from the light. WebPositive tropisms respond by moving toward the source of the stimulus as is the case in phototropism. The mechanism of this response is regulated by blue light stimulation and auxin accumulation. Blue light, a higher-energy wavelength contained within white light, stimulates the side of the plant facing the light source.
