WebPhototaxis. When an organism is responding to a stimulus of light, it is exhibiting Phototaxis. Euglena is a beautiful organism and it always moves toward the source of light thus exhibits positive Phototaxis. On the other hand, cockroaches, silverfish, slugs, and earthworms will always try to move away from the source of light and will exhibit ... 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 ).
