WebBacterial flagella are filamentous organelles that drive cell locomotion. They thrust cells in liquids (swimming) or on surfaces (swarming) so that cells can move toward favorable environments. At the base of each flagellum, a reversible rotary motor, which is powered by the proton- or the sodium-motive force, is embedded in the cell envelope. WebFlagella (singular: flagellum) and cilia (singular: cilium) are two types of cellular structures that allow movement in most microorganisms and animal cells, but not in high plant cells. Both flagella and cilia look like beating, hair-like appendages growing on the surface of cells. Usually, flagella are much longer than cilia.
