  1. Six Kingdoms of Life

  2. Domain Kingdom

  3. Archaea • Prokaryotes • Unicellular • Most are heterotrophs • Some autotrophs use chemosynthesis • DNA, ribosomes, cell wall • Cell wall does not contain peptidoglycan • Asexual & sexual reproduction

  4. Types of Archaea • Heat-loving • Live in hot, acidic environments – hot springs, thermal vents, around volcanoes • Salt-loving • Live in salty environments – salt lakes, Dead Sea • Methane-making • Live in swamps and in human intestines • Use CO2 during respiration and expel methane gas as waste

  5. Eubacteria • Prokaryotes • Unicellular • Most heterotrophs • Cyanobacteria photosynthesize • DNA, ribosomes, cell wall • Cell wall contains peptidoglycan • Asexual & sexual reproduction

  6. Shapes of Eubacteria • Cocci – sphere shaped • Bacilli – rod shaped • Spirilli – spiral shaped

  7. Bacteria – Human Diseases

  8. Domain Kingdom

  9. Protists – “odds and ends” • Eukaryotes • Some unicellular, some multicellular • Some autotrophs, some heterotrophs • Cell wall – various composition • Cellulose, algin, agar, calcium carbonate, silica • Asexual & sexual reproduction

  10. Protists – three types • Animal-like - Protozoa - unicellular • Heterotrophs – eat other organisms • Ex. Amoebas, ciliates, paramecia • Plant-like – Algae (one or more cells) • Autotrophs – photosynthesize • Ex. Giant kelp, algae • Fungus-like • Heterotrophs – absorb nutrients from decaying organisms • Ex. Slime mold, water mold

  11. Fungi • Eukaryotes • true nucleus & membrane bound organelles • Most multicellular (yeast unicellular) • Heterotrophs – digest food before consuming • absorb nutrients from decaying organisms • parasitic – absorb nutrients from a living host • mutualistic - lichens • Cell wall – made of chitin • Asexual & sexual reproduction

  12. Plants • Eukaryotes • Multicellular • Autotrophs • Specialized tissues and organs • Cell wall contains cellulose • Sexual reproduction

  13. Animals • Eukaryotes • Multicellular • Heterotrophs • Specialized tissues and organs • Do not have a cell wall • Sexual Reproduction
