What is phototaxis?
Phototaxis is a behavioral response exhibited by certain organisms in which they move towards or away from a source of light. This movement is often seen in simple organisms like bacteria, algae, and insects as a way to navigate their environment or seek out resources.
Is a behavior in which animals move toward or away from a light source?
Phototaxis is the behavior in which animals move toward (positive phototaxis) or away from (negative phototaxis) a light source. This behavior is commonly observed in various organisms, such as insects, plants, and microorganisms, as they respond to light stimuli for navigation, finding food, or avoiding predators.
A bacterial cell moving toward light would be an example of?
positive phototaxis.
