This chapter explores the classification of organisms into the 6 kingdoms: Eubacteria, Archaebacteria, Protists, Fungi, Plants, and Animals. It provides an overview of the characteristics, cell structure, and lifestyles of each kingdom.

The 6 Kingdoms Chapter 17
The 6 Kingdoms • All organisms are classified into 6 kingdoms: • 1) Eubacteria • 2) Archaebacteria • 3) Protists • 4) Fungi • 5) Plants • 6) Animals
Eubacteria Kingdom (“Monera”) • Unicellular (1 cell) • Prokaryotes (no nucleus) • Have cell walls w/peptidoglycan • Auto- and Heterotrophic • Very diverse • Some photosynthetic; some aerobic (need oxygen) • i.e.: E. coli
Archaebacteria Kingdom (“Monera”) • Unicellular • Prokaryotes • Cell walls lack peptidoglycan (weaker) • Many are anaerobic (NO oxygen) • Live in EXTREME environments • Auto- and Heterotrophic • i.e.: halophiles
Protista Kingdom • NOT fungus, plant, or animal (“leftover” group) • Mostly unicellular • Eukaryotes (have a nucleus) • Auto- and Heterotrophic • Some photosynthetic • i.e.: diatoms
Fungi Kingdom • Uni- or Multicellular (many cells) • Eukaryotes • Heterotrophs (eat other organisms) • Cell walls w/chitin • Most are decomposers (break down waste) • i.e.: mushrooms, yeast
Plant Kingdom • Multicellular • Eukaryotes • Autotrophs (make their own food) • Photosynthetic • Non-mobile (do not move) • Cell walls w/cellulose • i.e.: flowers, trees, etc.
Animal Kingdom • Multicellular • Eukaryotes • Heterotrophs • No cell wall • Most are mobile • VERY diverse • i.e.: insects, reptiles, humans, etc.
