- grouping organisms by their characteristics or features. The more characteristics used to group the more reliable the classification

Smaller groups can be grouped into larger groups...

  • Kingdom      e.g. Animalia
  • Phylum        e.g. Chordat
  • Class           e.g. Mammalia
  • Order           e.g. Carnivora
  • Family          e.g. Canidae (dog family)
  • Genus          e.g. Canis
  • Species        e.g. Canis Lupus (domesticated dog)


- a group of similar phyla                                                   

  • Animalia (animals)                      Multicellular- body of many cells  
    • Multicellular                              Heterotrophically- eat other organisms
    • no cell walls                              Saprophytically- digest food outside of the body
    • no chlorophyll                           Autorophically- make their own food
    • fedd heterotrophically               Unicellular- body of a single cell
  • Plantae (plants)
    • Multicellular
    • hace cell walls
    • have chlorogphyll
    • feed autotrophically
  • Fungi
    • Multicellular
    • have no cell walls
    • no chlorophyll
    • feed saprophytically
  • Protoctista
    • Mostly unicellular
    • nucleus
  • Prokaryotae
    • unicellular
    • no nucleus in cell

Vertebrates and Invertebrates

- In a phylum 'Chordata' the animals have a supporting rod running across their back, many animals in the chordata are vertebrates

Vertebaret grups split in to five groups...

  • Oxygen absorbtion- some use gills others use their lungs
  • Fertilisation- inside the body (internal fertilisation), outside the body (external fertilisation)
  • Reproduction- young born alive (viviparous), lay eggs (oviparous)
  • Thermoregulation- controlling their body temperatre (homeotherm), body temperature varies with enviroment (poikilotherm)
