The concentration of auxin differs in different parts of the plant in response to the direction of light. For example, in a stem the concentration of auxin is more in the parts which are away from the light. Presence of auxin hormone increases the cell division in that part. This causes the stem to bend towards the light. That is how phototropism occurs in plants.
