An organism’s response to an external or an internal stimulus is known as its behavior. Plant movement is one of the examples of plant behavior. The plants respond to light, gravity, and sometimes touch. Photoreceptors are light sensors produced by plants in order to sense the direction and amount of light received for several plant activities which require the proper amount of light.
