flagella

Advanced 🏥 Healthcare / Medical

Definition

The whip-like tail appendages that bacteria and some single-celled organisms use to swim around like microscopic Olympic swimmers. These protein-based propellers spin at ridiculous speeds to move the organism toward food or away from danger. It's basically nature's outboard motor, but at a scale that makes nanotechnology look huge.

Example Usage

The bacterium's flagella rotated at over 100 revolutions per second, propelling it through the culture medium.
