Overview of the Six Kingdoms: Prokaryotes to Eukaryotes in Life’s Domains

1. 6 Kingdoms

2. Two Domains ProkaryaEukarya EubacteriaProtista ArchaebacteriaPlantae Fungi Animalia

3. Eubacteria • Cell Type – Prokaryote • Cell structures – No membrane bound organelles only cytoplasm, membrane, cell wall, ribosomes, cell wall contains peptidoglycan • Organization – Unicellular • Nutrition – absorb or photo-/chemio- synthesis • Reproduction – binary fission, form spores with ability to remain dormant for long periods • Environment – ubiquitous: soil, water, other organisms --pathogenic • Examples – salmonella, tetnus, E. coli

5. Archaeabacteria • Cell Type – Prokaryote • Cell structures – No membrane bound organelles only cytoplasm, membrane, cell wall, ribosomes, cell wall lacks peptidoglycan • Organization – Unicellular • Nutrition – absorb or photo-/chemio- synthesis • Reproduction – binary fission, do not form spores • Environment – extreme conditions heat, salt, pressure, anaerobic -- non pathogenic Examples – Thermoproteus, Halococcus

7. Protists • Cell Type – Eukaryote • Cell structures – Nucleus, mitochondria, ribosome, etc • Organization – Unicellular (some multi but not specialized into tissues) • Nutrition – absorb, ingest or photosynthesis • Reproduction – asexual, sexual • Environment – aquatic (marine or fresh) • Examples – amoeba, Euglena, Paramecium

9. Plants • Cell Type – Eukaryote • Cell structures – Cell wall of cellulose, chloroplasts, nucleus, mitochondria, ribosome, etc • Organization – Multicellular • Nutrition –photosynthesis • Reproduction – asexual, sexual • Environment – terrestrial • Examples – dandelion, blue spruce tree

11. Fungi • Cell Type – Eukaryote • Cell structures – Cell wall (contains chitin) nucleus, mitochondria, ribosome, etc • Organization – Multicellular often multi nucleate, • Nutrition – absorb – extra cellular digestion, decomposer • Reproduction – asexual, sexual • Environment – terrestrial (trees), aquatic, on plants and animals • Examples – mushroom, mold, yeast

13. Animalia • Cell Type – Eukaryote • Cell structures – Nucleus, mitochondria, ribosome, etc • Organization – Multicellular • Nutrition – ingest • Reproduction – asexual, sexual • Environment – terrestrial, aquatic, soil • Examples – sponge, starfish, butterfly, human
