Study Notes

Classification and Characteristics of Multicellular Organisms

  • Organisms are classified using taxonomy, with the largest category being domain, based on cell type
  • Three main domains: Eubacteria, Archaebacteria, Eukarya
  • Eubacteria and archaebacteria are unicellular prokaryotes, Eukarya are more complex and basis of multicellular organisms
  • Evolutionary relationships between domains determined through protein and ribosomal RNA patterns
  • After domains, organisms sorted into Kingdom, Phylum, Class, Order, Family, Genus, Species
  • Multicellular autotrophs belong to Plantae (contain chloroplasts for photosynthesis) and Protista (including kelp)
  • Multicellular autotrophs in kingdom Protista and Plantae differ in specialized cells, such as chloroplasts
  • Multicellular heterotrophs are in Animalia (motile, must eat for energy) and Fungi (non-motile, gain food through extracellular digestion)
  • Multicellular organisms have specialized cells, communication systems, transport systems, eukaryotic cells, and increase in size with cell number
  • All plants are multicellular autotrophs, immotile, with specialized tissues and organs for communication and transportation
  • All animals are multicellular, motile, and heterotrophic, requiring food for energy
  • Examples of multicellular organisms include trees, grass, animals like fish and cheetahs, and fungi like mushrooms
