Study Notes

Levels of Classification

  • Kingdom is the broadest level of biological classification.
  • Class follows phylum in the hierarchical classification system.
  • Family is the classification level between order and genus.
  • Taxonomy is the branch of science that classifies organisms, including naming and categorization.
  • Species represents the most specific category in classification.
  • Order comes after class in the classification hierarchy.
  • Classification organizes organisms into categories based on shared characteristics.
  • Genus is the classification level that follows family.

Classification Systems

  • Binomial nomenclature uses a two-word format for organism naming: genus name followed by species name.
  • Phylum is the classification level that comes after kingdom.

Biological Kingdoms

  • Archaea includes ancient bacteria that can survive in extreme environments.
  • Plantae is the kingdom comprising multicellular plants.
  • Animalia consists of complex multicellular organisms, primarily heterotrophic (consume their own food).
  • Fungi are complex organisms that absorb nutrients from their environment.
  • Bacteria refers to kingdoms containing simple unicellular organisms.
  • Protista includes unicellular organisms that are more complex than bacteria and archaea.
