Later it was discovered that even the kingdom protista should be split into three. Taxonomists decided that this five-kingdom classification system is too simple. Microbiologists suggestes that organisms should be split into 3 main domins: bacteria, archaea, and. Bacteria: are prokaryotes that are usually single celled organisms. Bacteria are found everywhere, even in some extreme environments. Some bacteria cause disease and death, whereas others play a more beneficial role helping human-kind sustain the ecosystem. Most bacteria are found to have peptidoglycan on their cell walls.
