Question

how does phototropism occur in plants?? ​

Answer 1

Phototropism is the growth of an organism in response to a light stimulus. The cells on the plant that are farthest from the light have a chemical called auxin that reacts when phototropism occurs. This causes the plant to have elongated cells on the furthest side from the light.
