"Photothermolysis" Natural Recordings by Native Speakers
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
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.
Phototrophic refers to the process or organisms that produce their own food through the use of light energy. This is a characteristic of plants and some other organisms such as algae and cyanobacteria, which contain chlorophyll, a pigment that captures light energy to power photosynthesis.
Phototropin is a type of photoreceptor protein found in plants, responsible for detecting blue light and controlling plant growth and development. It plays a key role in phototropism, the phenomenon of plants growing towards or away from light sources. Phototropin is particularly important for regulating plant responses to light, such as cell elongation, cell division, and chloroplast movement, which help plants position themselves optimally to maximize their exposure to light.
