WebJul 18, 2024 · Flagella (singular: flagellum) are long, thin, complementary whips attached to bacterial cells that allow bacterial movement (motility). Bacterial cells generally have a diameter of between 0.1 microns and 50 microns, but on average around 2 microns. WebDec 24, 2024 · Movement produced by type IV pili is typically jerky, and so it is called “twitching motility,” as distinct from other forms of bacterial motility, such as motility produced by flagella. However, some bacteria, for example Myxococcus xanthus, exhibit gliding motility.
