Flagellum - Wikipedia
网页A flagellum (/ fləˈdʒɛləm /; pl.: flagella) (Latin for 'whip' or 'scourge') is a hairlike appendage that protrudes from certain plant and animal sperm cells, from fungal spores (zoospores), and from a wide range of microorganisms to provide motility. [1][2][3][4] Many protists with flagella are known as flagellates.
Flagellate - Wikipedia
网页A flagellate is a cell or organism with one or more whip -like appendages called flagella. The word flagellate also describes a particular construction (or level of organization) characteristic of many prokaryotes and eukaryotes and their means of motion.

Locomotion - Flagella, Movement, Prokaryotes | Britannica
网页Flagellar movement, or locomotion, occurs as either planar waves, oarlike beating, or three-dimensional waves. All three of these forms of flagellar locomotion consist of contraction waves that pass either from the base to the tip of the flagellum or in the reverse direction to produce forward or backward movement.

Flagella: Structure, Arrangement, Function • Microbe Online
网页Flagella (singular, flagellum) are the locomotory structures of many prokaryotes. Most protozoa and some bacteria are motile. Protozoa use flagella, cilia, or pseudopods, whereas motile bacteria move only using flagella. The flagellum functions by rotation to push or pull the cell through a liquid medium.
