1. Classification of All Organisms

2. Domain Bacteria Kingdom Eubacteria
billion years ago
2. Prokaryote
A cell with no nucleus or membrane-bound organelles
3. Unicellular
Cell walls w/peptidoglycan
a carbohydrate found in the cell walls of eubacteria

3. 5.Autotroph/Heterotroph
Autotrophs can make their own food.
Heterotrophs need to feed off an outside food source.
6. "True bacteria"like E.coli
7. 10,000 species
8. Motile

4. Domain Archaea Kingdom Archaebacteria
This kingdom of bacteria was not recognized until the late 1990's.
Evidence shows that these bacteria are more different from eubacteria than we are from plants!

5. 3.5 billion years ago
2. Prokaryote
3. Unicellular
4. Cell walls without peptidoglycan
5.Autotroph/Heterotroph
6. "Extremists" salt, hot, no oxygen
species
8. Motile

6. Domain Eukarya A. Kingdom Protista
First Eukaryotes!
Organelles came from aerobic and photosynthetic prokaryotes.

7. 1. 2 billion years ago
2. Eukaryote
Eukaryotic cells have a nucleus and membrane-bound organelles.
Uni or multi cellular or colonial like Volvox

8. 4. Plant-like protists have cell walls with cellulose
tough carbohydrate fiber, the main component in wood and paper.
5. Autotroph/Heterotroph
6. Animal-like - amoeba
Plant-like - algae, seaweed
Protists, prior to the late 1800's, were classified as either plants or animals depending on their characteristics.
7. 200,000 species
8. Most motile

9. B. Kingdom Fungi
It wasn't until the 1950's that Fungi became its own kingdom. This distinction was made because Fungi could not make their own food.

10. million years ago
2. Eukaryote
3. Multicellular -except for yeast

11. 4. Cell walls with chitin
Chitin is a complex carbohydrate that is also found in the external skeletons of insects!
5. Heterotroph
6. 100,000 species
Mushrooms, molds, yeast, athlete's foot
Mostly nonmotile

12. C.Kingdom Plantae
Mosses were the first land plants. They evolved from plant-like protists like seaweed.

13. million years ago
2. Eukaryote
Multicellular
Cell walls with cellulose
5. Autotrophs
6. 500,000 species
7. Flowers, ferns, oaks, pines
8. Nonmotile

14. D. Kingdom Animalia 95% of all animals are invertebrates.
Most of these are insects!

15. million years ago
2. Eukaryote
3. Multicellular
No cell walls
Heterotrophs
1.5 million species
Sponges, worms, fish, mammals
8. Motile
