a lash-like appendage used for locomotion (e.g., in sperm cells and some bacteria and protozoa)

A young, flexible shoot of a plant; esp., the long trailing branch of a vine, or a slender branch in certain mosses.

A long, whiplike cilium. See Flagellata.

An appendage of the reproductive apparatus of the snail.

A lashlike appendage of a crustacean, esp. the terminal ortion of the antennae and the epipodite of the maxilipeds. See Maxilliped.

A whiplike motility appendage present on the surface cells. Prokaryote flagella are composed of a protein called FLAGELLIN. Bacteria can have a single flagellum, a tuft at one pole, or multiple flagella covering the entire surface. In eukaryotes, flagella are threadlike protoplasmic extensions used to propel flagellates and sperm. Flagella have the same basic structure as CILIA but are longer in proportion to the cell bearing them and present in much smaller numbers. (From King & Stansfield, A Dictionary of Genetics, 4th ed)

A single long cilium.

The lash-like process of many Protista; a long slender runner or creeping stem.

A slender lash-like cilium.

Pl. flagella. A whiplike protoplasmic process attached to cells or to bacteria or other motile fungi and serving as an organ of locomotion; especially a long vibratile filament which serves as an organ of locomotion. [Lat.]

n. [Latin] A long branching shoot of a plant;—an appendage to the legs of some crustaceous animals having resemblance to a whip.
