1. CLASSIFICATION & 6 KINGDOM REVIEW NOTES

2. Why do scientists classify organisms?
To organize the diversity of life
2. To help us know what we are talking about
Ex. Brown animal – beaver or bison?

3. Classification Systems
In order to work well, a classification system must be established and logical
Furthermore, classification rules must have real biological meaning, so that you can identify an organism in the field
Don’t use (too broad): tall, colors, big, small
Do use (specific): greater than 2 meters in height, large eyes compared to head size, tail longer than body

4. Classification Systems Cont.
We use the classification system developed by Carolus Linneaus.
His classification system consists of 7 levels; they are:
Kingdom, Phylum, Class, Order, Family, Genus, species

5. Classification System
Hint Levels Example Broadest
Daring Domain Eukarya
King Kingdom Animalia
Phillip Phylum Chordata
Came Class Mammalia
Over Order Carnivora
For Family Canidae
Green Genus Canus
Spagetti species familiaris Most specific

6. In this classification system, each organism has a two-part scientific name; this system of naming organisms is called binomial nomenclature
In particular, organisms must have a universally accepted name.

8. We use Latin to name organisms, why?
1. It is a dead, unchanging language
2. There is no competition among countries

9. Every scientific name has 3 parts:
1. The entire name is italicized or underlined. You NEED to UNDERLINE!
2. The name is made up of the Genus and species names of the organism
3. The first word is capitalized and the second is lowercase.
Examples: Homo sapiens, Canus familiaris, Equus caballus

10. THE 6 KINGDOMS

11. Archaebacteria Domain: Archaea Cell type: Prokaryotic
Structures: Ribosomes, cell wall
Unicellular
Ex: Methanogens & Halophiles

12. Eubacteria Domain: Bacteria Cell type: Prokaryotic
Structures: Ribosomes, cell wall
Unicellular
Nutrition: Autotrophic or
heterotrophic
Ex: Common bacteria (staph, strep)

13. Protista Domain: Eukarya Cell type: Eukaryotic Unicellular Nutrition:
Autotroph or Heterotroph
Ex: Ameba, Euglena, Paramecium

14. Fungi Eukaryotic Nucleus, mitochondria, cell wall of chitin
Heterotroph
Mold, Yeast, Ringworm, Mushrooms

15. Plantae Eukaryotic Multicellular Autotrophic
Mosses, Ferns, Grass, Trees, Flowering plants

16. Animalia Eukaryotic Nucleus, mitochondria, lysosome Multicellular
Heterotrophic
Snakes, Worms, Dogs, Sponges, Insects, Humans
