Question
The following picture shows which tropism?
- Hydrotropism
- Geotropism
- Phototropism
- None of the above
Hint:
Water related tropism.
The correct answer is: Hydrotropism
The correct option is a) Hydrotropism.
In the picture we see that the root of plant was growing downwards. Then, when water was added to one side of the pot, the root changed its direction and started growing towards the water. This movement or growth of roots of plants towards or away from water is hydrotropism. In the picture it is positive hydrotropism as the roots move towards water.
