Kingdom (biology) facts for kids
Traditionally, some textbooks from the United States used a system of six kingdoms (Animalia, Plantae, Fungi, Protista, Archaea/Archaebacteria, and Bacteria/Eubacteria) while textbooks in countries like Great Britain, India, Greece, Australia, Latin America and other countries used five kingdoms (Animalia, Plantae, Fungi, Protista and Monera).
Definition and associated terms
There are 5 or 6 kingdoms in taxonomy. Every living thing comes under one of these kingdoms and some symbionts:
- Prokaryotes or Monera – the most simple living things: bacteria and archaea
- Protista – eukaryotes that are not plants, fungi, or animals
- Fungi – mushrooms, moulds and other fungi
- Plantae – all plants, such as moss, trees and grass
- Animalia – all animals, including people. See List of animal phyla
When Carl Linnaeus introduced the rank-based system of nomenclature into biology in 1735, the highest rank was given the name "kingdom" and was followed by four other main or principal ranks: class, order, genus and species. Later two further main ranks were introduced, making the sequence kingdom, phylum or division, class, order, family, genus and species. In 1990, the rank of domain was introduced above kingdom.
