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. WebPhototaxis is a kind of locomotory movement that occurs when a whole organism moves towards or away from light. This is good for phototrophic organisms as they can orient themselves most efficiently to receive light …
