Taxonomy - The science of describing, naming and classifying organisms.

3. Carolus Linnaeus 18th century & Swedish
He classified living things into 2 groups
plants
animals
He classified all living organisms according to similarities in shape and structure.

4. Carolus Linnaeus Founded modern taxonomy (science of classification)
He developed the binomial nomenclature - a two-part scientific name
Genus– the first part of the name (Upper Case)
Specific - second part of the name (Lower case)
Example – Tyrannosaurus rex)
Genus
Specific

5. 7 Levels of Classification
1.) Kingdom (Animaliae) – animal
2.) Phylum (Chordata) –backbone
3.) Class (Mammalia) – nurse young
4.) Order (Primate) – hands/feet
5.) Family (Hominidae) – walk upright
6.) Genus (Homo) –human
7.) Species (sapiens) – wise

13. Domain Archaea Prokaryotic Single-Celled Both heterotroph or autotroph
First discovered living in extreme environments, where other organisms could not survive. Some archaea can also be found in moderate environments, such as the open ocean.
Examples: Rings around the edge of the hot spring in Yellowstone National Park

14. Domain Bacteria Prokaryotic Single-Celled
Can be both heterotroph or autotroph
Examples: E.coli, salmonella, MRSA (Staph Infection)

15. Domain Eukarya
All organisms whose cells have a nucleus and membrane-bound organelles are called eukaryotes.
Four kingdoms:
Protista
Fungi
Plantae
Animalia

16. Kingdom Protista Eukaryotic Single-Celled
Both Autotroph and heterotroph
Examples: Algae, Euglena, Amoeba, Paramecium

17. Kingdom Fungi Eukaryotic Single & Multi- Celled Heterotroph Examples:
Yeast (single)
Mold, mildew, mushrooms (multi)

18. Kingdom Plantae Eukaryotic Multi-Celled Autotroph Examples:
Ferns, Flowering Plants, Tree

19. Kingdom Animalia Eukaryotic Multi-celled Heterotroph Examples:
sponge, dog, cat, monkey
