Question

Is the flagellum the organ of motility?

Answer 1

Flagella in bacteria:

1. In bacteria, the flagellum is the organ of the movement.
2. A cell's flagellum is a tiny hair-like structure that aids in movement.
3. Bacterial flagella have a single-stranded, helical structure and are comprised of flagellin protein.
4. The flagellum is a motility organelle that permits chemotaxis and movement to occur.
5. Bacteria can have one or more flagella and they can be either polar (with one or more flagella in one site) or peritrichous (with one or more flagella in numerous locations/several flagella all over the bacterium).
