What to Focus On

  • Classification makes the study of living organisms simpler and more meaningful.
  • Aristotle used visible body features for early classification.
  • Linnaeus developed the Two Kingdom system with Plantae and Animalia.
  • Bacteria are the sole members of Monera.
  • Monera are prokaryotic and lack a nuclear membrane.
  • The bacterial cell wall is non-cellulosic.
  • Protista includes all single-celled eukaryotes.
  • Protista boundaries are not well defined.
  • Protists are mainly aquatic.

Common Mistakes to Avoid

All organisms with a cell wall belong to Kingdom Plantae.

Viruses are part of the five-kingdom classification because they are infectious like living organisms.

Paramoecium and Amoeba are animals because they move and were earlier grouped with animal-like organisms.
