"Phototoxic" Natural Recordings by Native Speakers
Phototoxicity, often referred to by its older term photo-toxicity, is an injury to living tissue as a result of exposure to light. Phototoxicity is often compared with phototoxic dermatitis, cutaneous phototoxicity and cutaneous phototoxic eruption.
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
It seems that "phototonous" is not a valid word in the English language. It is possible that it may be a misspelling, a coined term, or a word from a specific dialect or technical context that I am not familiar with. Please provide more context or information about where you encountered this word, and I'll do my best to help.
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.
