  • With an amazing diversity of more than 2 million kinds of organisms, there is a need for CLASSIFICATION.

  • Classification allows us to group living organisms systematically according to their common characteristics;recognise relationships between different living organisms; andhave an easy reference in identifying living organisms.

  • Organisms are classified into FIVE KINGDOMS

  • Kingdom AnimaliaInvertebrates (with no backbone)Without jointed legsWith jointed legs Vertebrates (with backbone)FishReptilesBirds AmphibiansMammals

  • InvertebratesAnimals without jointed legsE.g. tapeworms, liverflukesHave flat, ribbon-like bodiesParasitesFlatworms

    E.g. pinworms, ascaris E.g. jellyfish E.g. spongesHave long, cylindrical bodies with pointed endsMany are parasitesSea animals with tentacles and stinging cells

    Large numbers of pores present on bodiesRoundwormsStinging-cell animalsSponges Animals without jointed legs

  • InvertebratesAnimals without jointed legs

  • Invertebrates)Animals with jointed legs (Arthropods)

  • Vertebrates

  • Kingdom Plantae

  • Flowering plantsHave roots, stems and leavesReproduce by seedsProduce seed-bearing fruits

  • Non-flowering plants

  • Dichotomous KeyClassifies objects or organisms based on observable features Splits a group into two contrasting groups each time it branches outCan be used to identify organisms
