Phototropism and gravitropism both involve the hormone auxin. In phototropism, auxin accumulates on the shaded side of the plant, causing the cells to elongate and bend towards the light source. In gravitropism, auxin also accumulates on the lower side of the plant, causing the cells to elongate and bend towards the ground or away from it depending on the plant organ.
