Classification of All Organisms

Domain Bacteria Kingdom Eubacteria 1. 3.5 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

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

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!

3.5 billion years ago 2. Prokaryote 3. Unicellular 4. Cell walls without peptidoglycan 5.Autotroph/Heterotroph 6. "Extremists" salt, hot, no oxygen 7. 100 species 8. Motile

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

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

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

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.

1. 400 million years ago 2. Eukaryote 3. Multicellular -except for yeast

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

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

1. 400 million years ago 2. Eukaryote Multicellular Cell walls with cellulose 5. Autotrophs 6. 500,000 species 7. Flowers, ferns, oaks, pines 8. Nonmotile

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

1. 600 million years ago 2. Eukaryote 3. Multicellular No cell walls Heterotrophs 1.5 million species Sponges, worms, fish, mammals 8. Motile
