Classification and evolution

• Animal kingdom features:

  • Eukaryotic, multicellular organisms
  • Almost all have specialised tissue
  • Heterotrophic, ingesting living or dead organic matter
  • Reproduction is generally sexual
• Plant kingdom features:

  • Almost all plants make food by photosynthesis (autotrophic)
  • Eukaryotic multicellular organisms which have chloroplasts and a cell wall made of cellulose
  • Reproduction is asexual and sexual
  • Majority have a transport system
• Fungi kingdom features:

  • Eukaryotic, unicellular or filamentous organisms
  • Non vascular (no xylem or phloem)
  • Non motile (not able to move by itself)
  • Reproduction by means of spores
  • Store their food in the form of starch
• Protist kingdom features:

  • They prefer aquatic or moist environments
  • Most have mitochondria
  • Mostly unicellular, eukaryotic organism
  • Reproduces asexually
• Monera kingdom features:

  • 70s ribosomes
  • Unicellular prokaryotes
  • DNA is naked and not bound by nuclear membrane
  • They reproduce asexually by binary fission or budding
  • Cell wall is made of peptidoglycan
• Taxonomy is the system of grouping living things according to their similarities and differences.
