Kingdom (biology)
From Simple English Wikipedia, the free encyclopedia
Kingdom is the highest rank used in the biological taxonomy of all organisms. Each kingdom is split into phyla.
There are 5 kingdoms in taxonomy. Every living thing comes under one of these 5 kingdoms. They are:
Monera - the most simple living things.
Protista - bacteria with only one cell.
Fungi - mushrooms, mold and other fungi.
Plantae - all plants, such as trees and grass.
Animalia - all animals, including people.

Sometimes entries in the table, which are next to each other, do not match perfectly. For example, Haeckel placed the red algae (Haeckel's Florideae; modern Florideophyceae) and blue-green algae (Haeckel's Archephyta; modern Cyanobacteria) in his Plantae, but in modern classifications they are considered protists and bacteria respectively. However, despite this and other failures of equivalence, the table gives a useful simplification.
