WebFeb 9, 2016 · The second requirement for phototaxis is motility. The third requirement is the ability to determine the direction of the incoming light, so that the cell can respond by moving in the appropriate direction. This final requirement, “knowing where the light is”, has been solved by evolution in a variety of ways in different organisms. WebPhototaxis is the process in which an organism alters its motility in response to light stimuli. This phenomenon is widespread in biology, encompassing complex multicellular organisms, unicellular eukaryotes, bacteria, and archaea. Here we will provide an overview of phototaxis in bacteria and archaea (prokaryotes). WebGiven the right cues, an organism will perform an innate behavior without the need for prior experience or learning.

WebPhototaxis is a directional locomotory movement seen in unicellular and multicellular phototactic organisms, which can be positive or negative. Positive phototaxis is a directional movement of cells towards the increasing light intensity, whereas negative phototaxis is a directional movement away from the increasing light intensity.
