Question

Use the scenario to answer the question.

You observe a potted plant that has been tipped over. Initially, its roots had been pointing left, but after a few days, the roots began to grow downward.

Select the type of geotropism that is being exhibited and where auxin is accumulating in the roots.

positive geotropism; auxin is accumulating on the top side of the root

positive geotropism; auxin is accumulating on the bottom side of the root
positive geotropism; auxin is accumulating on the bottom side of the root

negative geotropism; auxin is accumulating on the bottom side of the root

Answer 1

positive geotropism; auxin is accumulating on the bottom side of the root

Explanation: roots grow toward gravity (positive geotropism). Auxin collects on the lower side of roots and inhibits cell elongation there, causing the root to bend downward.
