Topics in Biological Classification

1

History and Need for Classification

  • Aristotle was the first to attempt scientific classification – he classified plants into trees, shrubs, and herbs, and animals into those with red blood and those without.
  • Linnaeus proposed the Two Kingdom Classification: Kingdom Plantae and Kingdom Animalia.
  • The Two Kingdom system was inadequate because it did not separate prokaryotes from eukaryotes, unicellular from multicellular organisms, and photosynthetic from non-photosynthetic organisms.
2

Five Kingdom Classification – Comparative Overview

  • Kingdom Monera: Prokaryotic cells, no nuclear membrane, cell wall of polysaccharide + amino acids (non-cellulosic), cellular body organisation, both autotrophic and heterotrophic nutrition.
  • Kingdom Protista: Eukaryotic cells, nuclear membrane present, cell wall present in some, cellular body organisation, both autotrophic and heterotrophic nutrition.
  • Kingdom Fungi: Eukaryotic cells, nuclear membrane present, cell wall made of CHITIN, multicellular/loose tissue organisation, heterotrophic (saprophytic/parasitic) nutrition.
3

Kingdom Monera

  • Bacteria are the SOLE members of Kingdom Monera.
  • Most abundant micro-organisms; found everywhere including extreme habitats (hot springs, deserts, snow, deep oceans).
  • Four shapes of bacteria: Coccus (spherical), Bacillus (rod-shaped), Vibrio (comma-shaped), Spirillum (spiral).
4

Kingdom Protista

  • All single-celled eukaryotes are placed under Protista.
  • Primarily aquatic; form a link between plants, animals, and fungi.
  • Have well-defined nucleus and other membrane-bound organelles.
