      • Plants: All green plants.
      • Fungi: Moulds, mushrooms, yeast.
      • Prokaryotes: Bacteria, nlue-green algae

    • Further Divisions
      • Phylum, Class,    Order,   Family, Genus, Species
    • Cladistics
      • Cladistics is another way to identify a species using DNA or RNA, rather than just physical characteristics
    • Vertibrates
      • Bony Fish: Breath through gills underwater, body temp varies depending on surroundings.External fertilisation and lay eggs.
      • Amphibians: Usually have lungs, can absorb oxygen through moist skin, body temp varies depending on surroundings.External fertalisation and lay eggs.
      • Reptiles: Have lungs and dry scales, body temp varies depending on surroundings. Internal fertilisation and produce eggs.
      • Birds: Have lungs, feathers and beaks. Can maintain their body temps (they're homeotherms) Internal fertilisation, lay eggs.
      • Mammals: Have lungs and fur. Can maintain body temp. Internal fertilisation and birth live young (they're viviparous)
