5 KINGDOMS CAMBRIDGE IN 5 MINUTES OUTLINE - Taxonomy - 5 Kingdoms - Prokaryotes vs eukaryotes - Key features of each of the 5 kingdoms TAXONOMY - The branch of science concerned with classification of organisms - Taxonomic hierarchy 5 KINGDOMS Animal Plant Fungus Bacteria Protoctist Features to consider: - Unicellular or Multicellular - Prokaryotic or eukaryotic? - Cell wall absent or present? - Autotrophic or heterotrophic? PROKARYOTES VS EUKARYOTES Eukaryote Prokaryote Cell membrane Cytoplasm Ribosomes DNA Small and simple Large and complex No membrane-bound organelles Membrane-bound organelles Nucleus, RER, mitochondria Nucleus, RER, mitochondria Circular DNA Linear DNA 5 KINGDOMS Uni/multi Eukaryotic/prokaryotic Cell wall Autotrophic/heterotrophic cellular Animal Multi Eukaryotic No Heterotrophic Plant Multi Eukaryotic Yes Autotrophic (cellulose) Fungi Multi Eukaryotic Yes Heterotrophic (chitin, glucans, glycoproteins) Protoctist Uni Eukaryotic Mostly no Autotrophic and (but some do) heterotrophic Bacteria Uni Prokaryotic Yes Autotrophic and (peptidoglycan) heterotrophic
