WebPhototropism is the directional response of a plant that allows the plant to grow towards or in some cases away from the light. Process of phototropism: Leaf tips and stem tips have a hormone called auxin which is sensitive to light. It allows the plant to positively grow towards the light source. This is called positive phototropism.
