1 answer
In the scenario where plants have been tipped over, auxin will influence cell growth in the roots by building up on the lower side of the root and inhibiting cell growth. This response leads to a curvature of the root that allows it to grow downward into the soil, which is known as positive geotropism.
Thus, the correct response is:
Auxin will build up on the lower side of the root and inhibit cell growth.
