describe how the plant hormone auxin and light affects the direction of growth of plants

The hormone auxin causes cells in shoots to grow faster, and cells in roots to grow more slowly. Auxin becomes more concentrated on the side of the plant that is not facing the light, the shaded side. In the shoots, this causes the shaded side to grow more quickly, meaning the shoot bends towards the light.In roots, the shaded side grows more slowly, meaning the root bends away from the light.
