|KINGDOMS OF LIVING THINGS|
|IN THE LINNAEAN CLASSIFICATION SYSTEM|
|1.||Monera *||small, simple single prokaryotic cell (nucleus is not enclosed by a membrane); some form chains or mats||absorb food||bacteria, blue-green algae, and
|2.||Protista||large, single eukaryotic cell (nucleus is enclosed by a membrane); some form chains or colonies||absorb, ingest, and/or photosynthesize food||protozoans and algae of various types||250,000+|
|3.||Fungi||multicellular filamentous form with specialized eukaryotic cells||absorb food||funguses, molds, mushrooms, yeasts, mildews, and smuts||100,000+|
|4.||Plantae||multicellular form with specialized eukaryotic cells; do not have their own means of locomotion||photosynthesize food||mosses, ferns, woody and non-woody flowering plants||250,000+|
|5.||Animalia||multicellular form with specialized eukaryotic cells; have their own means of locomotion||ingest food||sponges, worms, insects, fish, amphibians, reptiles, birds, and mammals||1,000,000+|
* A growing number of researchers now divide the Monera into two distinct kingdoms: Eubacteria (the true bacteria) and Archaebacteria (bacteria-like organisms that live in extremely harsh anaerobic environments such as hot springs, deep ocean volcanic vents, sewage treatment plants, and swamp sediments). Viruses, prions, and other non-cellular entities are not included in the five kingdoms.
