Detailed explanation-1: -Flagellum is primarily a motility organelle that enables movement and chemotaxis.

Detailed explanation-2: -Flagella propel bacteria through the body The rotation of the filament allows bacteria to move around in their environment. The motor embedded in the bacterial cell membrane rotates-just as a car motor spins beneath the hood of the vehicle-to drive the movement of the filament outside.

Detailed explanation-3: -Bacterial flagella are filamentous organelles that drive cell locomotion. They thrust cells in liquids (swimming) or on surfaces (swarming) so that cells can move toward favorable environments.

Detailed explanation-4: -Some bacteria have a single, tail-like flagellum or a small cluster of flagella, which rotate in coordinated fashion, much like the propeller on a boat engine, to push the organism forward. The hook: Many bacteria also use appendages called pilli to move along a surface.
