Vedclass · Answer

(C) The geotropic response in roots is primarily due to the redistribution of auxin. When a root is placed horizontally,auxin accumulates on the lower side due to gravity. In roots,a high concentration of auxin inhibits cell elongation. Therefore,the cells on the upper side grow faster than those on the lower side,causing the root to bend downwards towards gravity (positive geotropism).
