From the drop down pick the correction definition for negative phototropism and positive phototropism.(1 point)
Negative phototropism is
. Positive phototropism is
Negative phototropism is the movement or growth of a plant away from a light source.
Positive phototropism is the movement or growth of a plant towards a light source.
