flagellum

the bacterium moves using its flagellum.

a flagellum is essential for the motility of many microorganisms.

some sperm cells have a long flagellum for swimming.

the flagellum helps the organism to navigate through water.

flagellum structures can vary significantly among different species.

researchers study the flagellum to understand bacterial movement.

the flagellum is composed of protein filaments.

in some organisms, the flagellum is used for both locomotion and feeding.

damage to the flagellum can impair the organism's ability to swim.

the flagellum can be a key factor in infection processes.
