Respuesta :
A plant would respond positively to gravity if a light source was placed below a plant.
TROPISM:
- Tropism is the movement of a plant or part of a plant in response to stimulus (light, heat, water).
- A plant's response to light is called phototropism while plants response to gravity is called geotropism.
- Ideally, a plant's shoot is positively phototropic while a plant's root is positively geotropic. Hence, if a light source is placed under a plant, the plant would respond positively to gravity.
