In roots, higher IAA on the shaded side inhibits growth, causing them to bend away from light during phototropism.
In roots, higher IAA concentration on the shaded side inhibits growth, causing the root to bend away from light during phototropism.

| Back | IAA concentration increase on the shaded side, growth is inhibited so the root bends away from the light |
