1 Domains, Kingdoms, and Phyla Grouping Organisms And Classification

2 Age of Life on Earth 3.5 billion years ago (prokaryotes came first) 1.5 million species have been named by classification system called taxonomy (to name and group organisms in a logical manner)

3 Domains 3 largest classification groups Archaea Eubacteria Eukarya

4

5 THREE Domains …Kingdoms Eubacteria Archaea Eukarya Prokaryotic (no true nucleus) (true nucleus) (true bacteria) (extreme (protists bacteria) fungi plants animals)

6 TAXONS Domain (3): Archaea, Eubacteria, Eukarya Kingdom (6) Phylum Class Order Family Genus Species

7 Comparing Prokaryotic and Eukaryotic PROKARYOTIC No true nucleus (called a nucleoid) smaller EUKARYOTIC True nucleus with a membrane larger Comparing prokaryotic and eukaryoticComparing prokaryotic and eukaryotic

8 Six Kingdoms: Get Handout

9 Two Domains are Prokaryotic Genetic material NOT in a nucleus (called a nucleoid instead) INCLUDES: 1.Eubacteria –true bacteria 2. Archaea – extreme bacteria (sometimes “archaebacteria”) Bacteria Youtube (Archaea and Eubacteria) (2:33)Bacteria Youtube (Archaea and Eubacteria)

10 Kingdom: Archaea or Archaebacteria) Prokaryotic –no true nucleus Cell walls with no peptidoglycan (see next slide ) Unicellular – one celled Live in most extreme environments

11 What is peptidoglycan? A cross-linked complex of polysaccharides (sugars) and peptides (proteins) found in the cell walls of bacteria polysaccharides peptides cell wallsbacteria

12 Kingdom: Archaea Thermophiles –love heat Psychrophiles –cold-loving Acidophiles –love acidic environments Halophiles-love salty Barophiles-high pressure (ocean bottom)

13 Archaea Examples Thermus aquaticus (Extremophiles Youtube)Extremophiles Youtube Found in hot springs

14 Archaea Examples A-thermophile B-halophile C-halophile D-carbonatphile E-halophile F-calcium carbonatphile -What are extremophiles?-What are extremophiles? (54 secs) -Extremophiles -Extremophiles (1:25) -Bozeman Biology: Archaea-Bozeman Biology: Archaea (7:16)

15 Kingdom: EUBACTERIA (true bacteria) Prokaryotic – no true nucleus (just a nucleoid) Cell wall with peptidoglycan Unicellular –one-celled Diverse environments and metabolism

16 Eubacteria (Common) Staphylococcus Anthracis bacillus Escherichia coli Streptococcus

17 Eubacteria Examples Neisseria gonorrhoeae Staphylococcus aureus(skin)

18 Domain: Eukarya HAVE A NUCLEUS (membrane around the Genetic material) Includes 4 Kingdoms: Protists Fungi Animals Plants

19 Kingdom: Protista Eukaryotic – DO have a nucleus Usually unicellular Varied cell walls (Plant-like, animal- like, fungus –like)

20 PROTISTA Plant-like protists (have chlorophyll) Animal-like protists (Move) Fungus-like protists (slime molds move like amoeba, decomposer)

21 Protista Examples Protist Youtube Protist Youtube EuglenaParamecium Volvox (colonial) Stentor

22 Kingdom: FUNGI Eukaryotic Cell walls of chitin – stiffener Can be multicellular or unicellular

23 Fungi Yeast (unicellular fungi) Can you see the budding?

24 More Fungi Bracket Fungus Toenail Fungus Bread mold

25 More Fungi Penicillium Black Mold Hot dog mold

26 Kingdom: Plantae Eukaryotic Cell wall made of cellulose Multicellular –more than one cell Autotrophic – photosynthetic – make their own food

27 What is cellulose? Stiff, interlocking fibers in plants

28 Examples:

29 Kingdom: Animalia Eukaryotic No cell wall Multicellular Heterotrophic –need to get food from other sources (plants and animals)

30 Animalia

31 What kingdom are you?
