(c) phototropism
(d) photosynthesis
Correct Answer:
phototropism
Explanation:
Thigmotropism is a directional curvature movement of growth which is produced in response to the stimulus of contact. It is most conspicuous in tendrils which coil around support and helps the plant in climbing. Phototropism is a paratonic directional growth movement of curvature which is induced and determined by the direction of light stimulus. Nastic movements are non-directional movements in which the response is determined by the structure of the responsive organ and not by the direction of the stimulus.
