What is the flagellum used for?

Explanation:
The flagellum is a whip-like tail that makes the cell swim. It works as a propeller, rotating or beating to push the cell through fluid, powered by motor proteins. This motion lets many cells, like bacteria and sperm, move toward nutrients or toward/away from conditions they encounter. While movement can help with feeding or reaching an egg in some cases, the flagellum’s primary job is locomotion, not sensing light, feeding, or reproduction.
