Auxin affects the growth of plant stems by building up on the side of the stem that is away from the light source and stimulating growth. This uneven distribution of auxin causes the cells on the shaded side to elongate more than those on the light-exposed side, resulting in the stem bending towards the light, a phenomenon known as phototropism.
