Question

what is the meaning of negative and positive phototropism

Answer 1

Answer:

Positive phototropism is growth towards a light source; negative phototropism is growth away from light. Shoots, or above-ground parts of plants, generally display positive phototropism—they bend toward the light.

Phototropism is the ability of a plant, or other photosynthesizing organism, to grow directionally in response to a light source. ... Positive phototropism is the response of a plant toward a light source, while negative phototropism (also called “aphototropism”) causes growth in the opposite direction.
