The six-kingdom system is a somewhat antiquated system of classification of living organisms. The more modern version of the classification is a three-domain system, where two of the three domains form their own kingdoms and the third splits into four kingdoms.
The kingdoms are as follows:
| Kingdom name | Names of things in the kingdom | Distinguishing feature set |
|---|---|---|
| animalia | animal | eukaryotic, multicellular, no cell wall, motile cells, heterotrophic, embryos go through a blastula stage |
| plantae | plant (also includes algae which are sometimes not thought of as plants) | eukaryotic, multicellular, cell wall composed of cellulose, autotrophic phototrophic possessing chlorophyll, have plastids |
| fungi | fungus | eukaryotic, multicellular, cell wall composed of chitin, heterotrophic saprotroph, |
| protista | protist | eukaryotic, unicellular, may be plant-like (protophyta) or animal-like (protozoa) |
| bacteria (also called eubacteria) | bacterium | prokaryotic, unicellular |
| archaaa (also called archaebacteria) | prokaryotic, unicellular |
