Bacterial cells can move by many ways, including "swimming" through water via the bacterial flagellum (although at the scale of a bacterial cell, the intermolecular forces between water molecules become so great that swimming would be more like drilling through sand or very thick mud). The bacterial flagellum has achieved some fame through the Intelligent Design movement as the poster boy ofirreducible complexity. However, science has now answered how the bacterial flagellum probably evolved (scientists have identified a structure very simple to the bacterial flagellum that injects poison into other cells) and Michael Behe's "theory" irreducible complexity is thoroughly debunked.
