Answer:
Phototropism is the growth of an organism in response to a light stimulus. Phototropism is most often observed in plants, but can also occur in other organisms such as fungi. The cells on the plant that are farthest from the light have a chemical called auxin that reacts when phototropism occurs.
Answer:
Phototropism is directional movement in which the stem grows towards light stimulus and roots grow away from light. ... This enhanced growth on one side causes the bending of the shoot towards the light.
