In biology, a kingdom is the top-level, or nearly the top-level, grouping of organisms in scientific classification. Originally, two kingdoms were distinguished, the Animalia (animals), which typically could move about, and the Plantae (plants), which typically could not.
Kingdoms. The first rank in this system is called a kingdom. There are five kingdoms, based upon what an organism's cells are like: 1  animalia (all multicellular animals). 2  plantae (all green plants). 3  fungi (moulds, mushrooms, yeast). 4  prokaryotae (bacteria, blue-green algae). 5  protoctista (Amoeba, Paramecium).
