WebPhototaxis is the orientation of free moving organisms to light. In plants, the free movement of the whole body is restricted to lower organisms, because only among them do we find freely moving organisms. In botany, such free moving phototaxis has been reported in diatoms, blue-green algae, bacteria, desmids, and many flagellates.

WebNov 8, 2024 · In chemotaxis, the direction of cellular locomotion is determined by a gradient of substances in the environment. The movement of cells toward a higher concentration of a stimulating substance is defined as positive chemotaxis (attractant), while the movement away is defined as negative chemotaxis (repellent).
