A Flagellum is a long, tail-like organelle in a [[cell]] that allows a cell to move around. It is made up of microtubules and surrounded by a plasma membrane.  

A '''Flagellum''' is a long, tail-like [[organelle]] in a [[cell]] that allows a cell to move around. It is made up of [[microtubule]]s and surrounded by a [[plasma]] [[membrane]].  

In single-cell organisms flagella move like a whip to provide propulsion to the cell. As part of a larger organism, their function is often to move fluids along mucous membranes. When they perform this function, they are called [[cilia]].

There are three types of flagella: [[eukaryote|eukaryotic]], [[archaeal]] and [[bacteria|bacterial]].
