Kingdoms
Organisms can be classified into groups according to characteristics that they share. The first big division of living things in the classification system is to put them into one of five kingdoms. These are based on what an organism's cells are like. The table shows the names of the kingdoms and examples of the sort of organisms they contain.
Kingdoms and organisms kingdom characteristics examples
Animals
Cells do not have a cell wall. Multicellular and feed on other organisms.All multicellular animals, including: jellyfish, worms, arthropods, molluscs, echinoderms, fish, amphibia, reptiles, birds and mammalsPlants
Cells have a cellulose cell wall. They uselight energy to produce food by photosynthesis.All green plants, including: algae, ferns and mosses (plants that do not produce seeds); conifers and flowering plants (plants that do produce seeds)Fungi
Cells have chitin cell walls. Reproduce using spores rather than seeds.Moulds, mushrooms, yeastProkaryotes
Have a cell wall but not made from cellulose. Cells have no nucleus.Bacteria, blue-green algaeProtoctistsAn ameoba, a simple unicellular organism
Exist as single cells or colonies of single cells.Amoeba, Parameci
