How does phototaxis help an organism survive
WebApr 27, 2016 · Several years ago, we showed that cellular reduction-oxidation (redox) poise acts as a strong signal that determines the phototactic sign: Cells show positive phototaxis after treatment with reactive oxygen species (ROS), whereas they show negative phototaxis after treatment with ROS-scavenging reagents ( 14 ). WebKinesis and taxis are two types of simple movement responses by motile organisms to various environmental stimuli like temperature, light, or humidity. These responses ensure …
