Analysis and explanation
Auxins are plant hormones that stimulate cell elongation and cell division. They are responsible for phototropism, which is the growth of plants towards light. When light is shone on a plant, auxins accumulate on the side of the stem away from the light, causing the cells to grow longer and the stem to bend towards the light.

Auxins are also involved in root growth and cell differentiation.
