"Phototaxy" Natural Recordings by Native Speakers
Phototaxy is not a commonly recognized word in the English language.
Phototaxy: Phototropy (noun)
Produced or formed through photosynthesis, a process in which green plants, algae, and some bacteria convert light energy, usually from the sun, into chemical energy stored in glucose.
Phototactism (or photoactism) is a rare term referring to a stimulus-response reaction to light. It can be seen as a form of phototropism, a phenomenon where an organism grows or moves towards or away from light. However, phototactism specifically describes a nervous response wherein an animal senses and reacts to light using its skin or other bodily tissues.For example, some invertebrates, such as sea creatures and certain worms, exhibit phototactic responses. When light is applied to their sensitive skin, they move towards (positive phototactism) or away (negative phototactism) from the light source in a reflex reaction. This is different from phototropism, which involves the actual growth towards or away from light sources, rather than just a reflex movement.
Phototaxis is the movement of an organism in response to the direction, magnitude, or quality of light. The movement is usually towards the source of light, a phenomenon called positive phototaxis, or away from the light, a phenomenon called negative phototaxis.
Photothermolysis is the selective heating of a target area of skin by high-intensity pulsed light (IPL) or a laser. It is a non-invasive treatment used to minimize the appearance of hair, pigment or vascular lesions, and/or to kill bacteria in the skin
