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.
Living organisms are classified into five kingdoms, such as Monera, Protista, Fungi, Animalia and Plantae. Kingdom protista is a special kingdom among these. All living eukaryotes, which cannot be included into other kingdoms such as Plantae or Animalia, are grouped altogether into one group called protista.
