1. Kingdom Monera and Prokaryotic Cells

Key Concepts & Definitions

  • Animalia: Multicellular, heterotrophic eukaryotic organisms that lack cell walls and primarily obtain nutrition through holozoic means.
  • Kingdom Monera: A kingdom consisting solely of bacteria, which are the most abundant microorganisms and inhabit extreme environments, classified based on cell structure and morphology.
  • Mycoplasma: Bacterial organisms that completely lack a cell wall, are the smallest living cells known, can survive without oxygen, and many species are pathogenic.
  • Viruses: Viroids, Prions, and Lichens Whittaker did not include these in the five-kingdom classification as they are not truly "living." ● Viruses: Non-cellular organisms characterized by having an in
