Three domains are Bacteria, Archaea, and Eukaryotes. Bacteria is found everywhere and in most habitats. They may possess more then one flagella and are basically unicellular although they are found in groups of multiple bacteria. Archaea are prokaryote and do not contain a nucleus or organelles, only a circular chromosome. They're also more primitive then Bacteria and can be found in extreme environments. Eurokaryotes have a nucleus and are much more complex then Bacteria/Archaea (Prokaryotes).
