Quizplus · Accepted Answer

Auxins are plant hormones that promote cell elongation and are responsible for the phototropic response. When a plant is tipped over, auxins will accumulate on the lower side of the stem, causing the cells to elongate more in that area and the plant to bend upward again. This is known as positive gravitropism. Cytokinins promote cell division and are not involved in gravitropism. Abscisic acid and ethylene are involved in stress responses and leaf senescence, respectively, but not in gravitropism.
