What is a flagellum in bacteria?
Quick Answer
A bacterial flagellum is a whip-like structure used for movement. It helps some bacteria swim through liquid or move toward nutrients.
The Full Story
A flagellum is a long, thread-like appendage that rotates like a tiny propeller in many motile bacteria. By spinning, it allows the cell to move through fluids and respond to chemical cues in its environment. This movement can help bacteria find food, avoid harmful conditions, or colonize hosts. Bacterial flagella are structurally different from the flagella of many eukaryotic cells.
