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.
