Changes

'''Archaea''' are [[prokaryote|prokaryotic]] [[organism]]s, lacking [[DNA]] and [[organelle]]s. They were previously thought to be [[bacteria]], but as it turns out, they are an entirely different breed. For example, the [[cell wall]]s of archaea don't contain [[peptidoglycan]], whereas the cell walls of bacteria do. Therefore, usage of the term bacteria to describe archaea is now obsolete.
