Auxin will build up on the lower side of the root and inhibit cell growth. This response is known as gravitropism, where roots grow downward in response to gravity, and auxin distribution causes the lower side of the root to have higher levels of auxin, leading to cell elongation inhibition on that side and promoting upward growth.
You observe the growth of a group of plants that have been tipped over.
How will auxin influence cell growth in the roots of these plants?
