flagellum

Bacterial propulsion appendage

A flagellum is a long, whip-like appendage that propels certain cells through liquid environments.

Bacteria use flagella to swim toward nutrients or away from toxins.

Sperm cells have flagella that drive them toward the egg.

The plural is flagella.

The word shares a root with flagellate, meaning to whip.
