9. Soooo……why use a scientific name?
There are at least 50 common names for the animal shown on the previous 7 slides.
Common names vary according to region.
Soooo……why use a scientific name?

10. Carolus Linnaeus
Swedish botanist that developed a two-word naming system (binomial nomenclature) and a classification system which includes seven Hierarchical taxa.

11. Linnaeus Seven Hierarchical Taxa:
The major classification levels, from most general to most specific. (several of these have subdivisions)
A group at any level is a taxon.

12. Example: Grizzly Bear Kingdom Animalia Phylum Chordata
Class Mammalia
Order Carnivora
Family Ursidae
Genus Ursus
Species Ursus arctos

13. Cladogram
Diagrams that shows the evolutionary relationships between living organism.

14. Domains and Kingdoms
Organisms are placed into domains and kingdoms based on:
their cell type
their ability to make food
number of cells that make up the organism.

15. The Three Domains Domain Archaea Domain Bacteria Domain Eukarya
Includes newly discovered cell types
Contains 1 kingdom – the Archaebacteria
Domain Bacteria
Includes other members of old kingdom Monera
Has 1 kingdom – the Eubacteria
Domain Eukarya
- Includes all kingdoms composed of organisms made up of eukaryotic cells
– Protista
– Fungi
– Animalia
– Plantae

16. Domain: Bacteria Kingdom: Eubacteria
Cell Type: Prokaryote (lacks a nucleus)
Cell Structure: Cell walls with Peptidoglycan
# of Cells: Unicellular (organisms consists of a single cell)
Mode of Nutrition: Autotroph or Heterotroph
Example: E. Coli

17. Domain: Archaea Kingdom: Archaebacteria
Cell Type: Prokaryote (lacks a nucleus)
Cell Structure: Cell walls without Peptidoglycan
# of Cells: Unicellular (organisms consists of a single cell)
Mode of Nutrition: Autotroph or Heterotroph
Example: Halophiles

18. Domain: Eukarya Kingdom: Protista
Cell Type: Eukaryote (Cells with a nucleus)
Cell Structure: Some cell walls with cellulose; some chloroplasts
# of Cells: Most unicellular; Some colonial; some multicellular.
Mode of Nutrition: Autotroph or Heterotroph
Example: Amoeba, Slime Molds

19. Domain: Eukarya Kingdom: Fungi
Cell Type: Eukaryote (Cells with a nucleus)
Cell Structure: Cell walls of Chitin
# of Cells: Most multicellular; some unicellular
Mode of Nutrition: Heterotroph
Example: Mushrooms, yeast

20. Domain: Eukarya Kingdom: Plantae
Cell Type: Eukaryote (Cells with a nucleus)
Cell Structure: Cell walls of cellulose; chloroplasts
# of Cells: Most multicellular; some green algae unicellular
Mode of Nutrition: Autotroph
Example: mosses, ferns

21. Domain: Eukarya Kingdom: Animalia
Cell Type: Eukaryote (Cells with a nucleus)
Cell Structure: No cell walls or chloroplasts
# of Cells: Multicellular
Mode of Nutrition: Heterotroph
Example: Sponges, worms, insects, fish, mammals
