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


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
No true nucleus (called a nucleoid) smaller EUKARYOTIC True nucleus with a membrane larger Comparing prokaryotic and eukaryotic

8 Six Kingdoms: Get Handout

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

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

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)
Found in hot springs Thermus aquaticus (Extremophiles Youtube)

14 Archaea Examples A-thermophile B-halophile C-halophile D-carbonatphile
E-halophile F-calcium carbonatphile -What are extremophiles? (54 secs) -Extremophiles (1:25) -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 HAVE A NUCLEUS Domain: Eukarya (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
Euglena Paramecium Stentor Volvox (colonial)

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

23 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?
