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.
Organisms are classified into three Domains and into one of six Kingdoms of life. These Kingdoms are Archaebacteria, Eubacteria, Protista, Fungi, Plantae, and Animalia. Organisms are placed into these categories based on similarities or common characteristics.
