WebOne common mechanism for bacteria to undergo random walks is the so-called "run and tumble" method. This method is used by bacteria that have several flagella (little whip-like propellers that help them swim). When rotating in one direction, the flagella all work together to propel the bacterium, creating a straight swim.
