Kingdom (biology)

Kingdom is the highest rank, after the domain, which is normally used in the biological taxonomy of all organisms. Each kingdom is split into phyla.

There are 5 to 7 kingdoms in taxonomy. Every living thing comes under one of these kingdoms and some symbionts, such as lichen, come under two. There are at least:

• 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
• Chromalveolata – plastids containing chlorophyll.
