Answer:
D) Negative Geotropism
Explanation:
The stem growing upright is a typical example of negative geotropism.
Geotropism is the growth of a part of plant towards the pull of gravity.
- Gravity always pulls down on every object.
- When a body grows downward, then it is responding to a positive geotropism.
- When a body begins to grow upward, again gravity, then it is negative geotropism.
In this case, the negative geotropism is exhibited by some plant roots.
Also, some tree branches can also grow downward and this shows positive geotropism
