WebFlagella: Bacteria can have one or more flagella (singular: flagellum). These can rotate or move in a whip-like motion to move the bacterium. Cell wall: WebSep 4, 2016 · Most bacteria have flagella; they are threadlike appendages extending from the surface of many microbes. They help move the organism around, a function called motility, in a rotating motion. Enabling a bacterium to get around seems to be pretty critical to pathogenicity; there is an association between infection and motility.
