WebWays how plants respond to stimuli: Because plants require sunshine to thrive, they will tilt or migrate towards the source of light. Phototropism is the name given to this type of movement. Negative phototropism occurs when a plant travels away from a light source. WebA tropism is the growth of a plant as a response to a stimulus, and phototropism occurs when a plant responds to light by bending in the direction of the light. Although plant physiologists (scientists who study how the processes of a plant actually work) know that this growth is caused by a plant hormone, they still do not fully understand ...

Phototropism is most often observed in plants, but can also occur in other organisms such as fungi. The cells on the plant that are farthest from the light contain a hormone called auxin that reacts when phototropism occurs.
