Some Bacteria can move using simple flagella that are attached with a unique wheel-like structure.
These are simpler in structure than the flagella seen in some eukaryote cells. Bacteria flagella, which may either cover the cell or from a tuft at one end can rotate rapidly, propelling the bacterium through its liquid environment. Recent research has revealed a unique wheel-like structure embedded in the bacterial membrane and cell wall that allows the flagellum to rotate. Flagella allow bacteria to disperse into new habitats to migrate toward nutrients, and to leave unfavorable environment. Flagellated bacteria show orientation toward various stimuli, a behavior called Taxis. Some are chemo tactic, moving toward chemicals given off by food or away from toxic chemicals.
