Answer:
See the answer below
Step-by-step explanation:
If the root of a plant grows away from the pull of earth's gravity, it will not produce any effect on the plant provided that other conditions of growth are kept normal.
According to research, the force of the Earth's gravity has no effect on the growth features of plants. Plants that were grown away from the influence of gravity still grew normally in a research conducted in space by NASA in 2010.
This thus means that the upward growth of the stem and the downward growth of the root in a negative and positive response to gravity respectively is dictated by the inherent attributes of plants themselves, and not by the force of the earth's gravity.
