Phototropism is one of the many plant tropisms or movements which are in response to external stimuli. In this case, the growth or movement is in response to the external stimulus - light. Growth towards a light source is called positive phototropism, while growth away from light is called negative phototropism. Therefore, shoot exhibits positive phototropism.
