What to Focus On

  • Species is the lowest and basic category.
  • Members of one species can interbreed and produce fertile young ones.
  • The hierarchy goes from Kingdom down to Species.
  • Genus contains similar species.
  • Family contains related genera.
  • Order contains related families.
  • Bacteria and fungi are not plants.
  • Euglena shows both plant-like and animal-like features.
  • Bread mould is multicellular but not a plant.

Common Mistakes to Avoid

Living organisms are best classified only into two kingdoms: plants and animals.

Species means any group of similar-looking organisms.

Hybrids like mule, Zenkey, Tigon, Geep, and Pomato are fertile because they are living offspring.
