1. CLASSIFICATION
methods of grouping things according to similarities or differences.
Ex. by size, color, age, etc.

2. Classifying organisms is called taxonomy.
- started by Aristotle in 350 BC.
Many disagreements about the groupings:
by air?
by sea?
by land?
Where to put frogs? Geese?

3. Today’s system is called binomial nomenclature (two-name naming)
- created by Carolus Linnaeus.
Ex. Canis lupus
Ex. Canis familiaris

4. Latin was used by scientists and scholars in the 1700’s.
used today to avoid the confusion of using many different languages.
Ex. Spanish moss
- not Spanish
- not moss

5. The Latin names are an organism’s Genus species.
Canis familiaris
Genus grouping
Species grouping
Always lower case.
Most precise
“smallest”
Can produce offspring that can produce offspring
Always capitalized
Both italicized

6. Acer rubrum ‘red maple’ Bison bison
Other examples:
Homo sapiens sapiens
Felis domesticus
Acer rubrum ‘red maple’
Bison bison

7. CLASSIFICATION CATEGORIES
there are eight different levels of scientific classifications.
it becomes more exact/specific as you “move down”.
Ex. Bottlenose Dolphin
Tursiops truncatus

8. Domain Eukarya
Kingdom Animal
Phylum Chordate
Class Mammal
Order Cetacea
Family Delphinadae
Genus Tursiops
Species truncatus

9. 3 Domains: Archaea, Bacteria, and Eukarya
Archaea and Bacteria
Prokaryotes: Cells have no nucleus
Kingdoms:
Archaebacteria
Eubacteria
Eukarya
Eukaryotes: Cells have nucleus
Kingdoms
Protist
Fungi
Plant
Animal

10. Six Kingdom Classification
Kingdom Animal
are multicellular.
can move from place to place.
Heterotrophs- cannot make their own food.

11. Autotrophs- make their own food through photosynthesis.
Kingdom Plant
Autotrophs- make their own food through photosynthesis.
Multicellular

12. - heterotrophs-can not make their own food.
Kingdom Fungi
-can not move.
- heterotrophs-can not make their own food.
- decomposers-absorb food from dead material.
Ex. mushrooms, mold, yeast.

13. - have traits of both plants and animals.
4) Kingdom Protist
-most are unicellular.
- have traits of both plants and animals.
Ex. Euglena
- can move but it has chloroplasts.

14. 6) Kingdom Archebacteria
5) Kingdom Eubacteria
Ex. strep.
6) Kingdom Archebacteria
Ex. stromatolites
both are prokaryotic.
unicellular.
Archebacteria are ‘older’ and more primitive and can live in harsh conditions.
The difference between them is their chemical make-up.

15. These kingdoms were formed when Kingdom Monera was split into two.
