Section 2 - The Six Kingdoms For hundreds of years, all living things were classified as either plants or animals.  But over time, scientists discovered species that did not fit easily into these two  categories. Organisms are classified by their characteristics. Bacteria are extremely small single-celled organisms that differ from all other living things. Bacteria are prokaryotes. Bacteria are divided into two kingdoms: archaebacteria eubacteria Archaebacteria archae - comes from Greek word meaning ancient. They are a kingdom made up of bacteria that live in extreme environments. Most living things could not survive in these environments.  For example, there are  bacteria living in hot springs in Yellowstone National Park. The yellow and orange rings around the opening are made of archaebacteria. Eubacteria A kingdom that contains all bacteria except archaebacteria. 1
