Photokinesis is a biological response exhibited by living organisms in which they move or orient themselves in response to light. This phenomenon is commonly observed in plants, animals, and microorganisms. In photokinesis, the intensity, direction, or wavelength of light can influence the movement or behavior of an organism. For example, some plants will turn towards a source of light, a behavior known as phototropism, while other organisms may move away from bright light, a behavior known as photophobia. Photokinesis is important for many organisms because it allows them to optimize their energy use, find food or mates, and avoid predators or unfavorable environments.
