flagella flagella  /flə ˈdʒɛ lə/

Definition(s):

  1. (n) a whip used to inflict punishment (often used for pedantic humor)
  2. (n) a lash-like appendage used for locomotion (e.g., in sperm cells and some bacteria and protozoa)

Usage(s):

  1. The micrographs clearly show membranes, nuclei, sometimes surrounding capsules and whiplike appendages called flagella.
  2. If, for instance, a hostile substance is introduced into its surroundings, the bacterium uses its flagella long, hairlike appendagesto swim away from it.
  3. Among other things, optical tweezers can keep a tiny organism swimming in place while scientists study its paddling flagella under a microscope.

    It's counterintuitive but true: Some microorganisms that use flagella for locomotion are able to swim faster in gel-like fluids such as mucus. Research engineers have now figured out why. It's the angle of the coil that matters.
