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.
Cells in Motion. Cilia and flagella are cellular appendages that are capable of specific types of movement. The movement of these appendages allows the cell to move or to fulfill specific tasks. Flagella are relatively long tail-like structures that are capable of either undulating or rotational movement.hese two types of flagella share the same basic purpose of cellular motion, but bacterial flagella have additional functions related to the special types of movement they can produce. Eukaryotic flagella exhibit a wiggling or undulating movement that serves primarily to propel an entire cell.
