Flagella are long, thread-like appendages which provide some live single cells with the ability to move, motility. Bacteria which have flagella are either rod or spiral-shaped and are known as bacilli and spirochetes, respectively. Cocci, or round bacteria, are almost all nonmotile.nimal sperm cells also have flagella. However, prokaryotic cells (such as bacteria) have flagella made up of the protein flagellin. Whereas, eukaryotic cells (such as sperm) which have a nucleus have flagella composed of tubulin proteins.

A flagellum (plural: flagella) is a long, whip-like projection of a cell composed of microtubules.They help propel cells and organisms in a whip-like motion. The flagellum of eukaryotes usually moves with an âSâ motion, and is surrounded by cell membrane.Flagella are structurally almost identical with the much smaller Cilia.lagellum is the one on the left, cilia are on the right.
