1. Taxonomy
How Life is organized

2. The Layout Kingdom Phylum Class Order Family Genus Species
King Philip Can Order Family Grown Squash

3. Dichotomous Questions
Prokaryotic(no nucleus) Vs. Eukaryotic(nucleus) Unicellular Vs. Multicellular Movement Vs. No Movement Sexual Reproduction Vs. Asexual Reproduction What do they eat?: -autotrophic -heterotrophic -Decomposer (detrivore)

4. The Six(or 5) Kingdoms Animalia: -Multicellular, eukaryotic
-Heterotrophic, Sexual/Asexual R.
-Movement at some life-stage
Plantae:- Multicellular, eukaryotic
-Autotrophic(green),Sexual/Asexual
-no movement within generations

5. 3. Fungus / Fungi: - Multicellular, Eukaryotic - Decomposers/Detrivores - No movement w/in generations - sexual/asexual reproduction 4. Eubacteria: - Unicellular - Heter/Autotrophic, Detrivore - Sexual/Asexual Repro. - Very Diverse - Prokaryotic

6. 5. Archaebacteria: -Unicellular -Heter/Autotrophic, Detrivore -Sexual/Asexual Reproduction -Prokaryotic -Live in Extreme Areas: -Methanogens -Extreme Halophiles -Thermoacidophiles

7. Protista: - Unicellular, Eukaryotic
- Sexual/Asexual Reproduction
- Heterotrophic/Autotrophic/Detrivore
Amoeba Paramecium

8. What is Taxonomy?
Taxonomy: a discipline where scientists classify organisms and assign each of them a universally accepted name.
- Categorizes organisms
- Universal to all languages since it’s in Latin
- Organisms are more related to others in
their group than to those in other groups.
Removes the confusion of common names:
cougar, mountain lion, Carolina panther,
Florida panther, Nittany lion.

9. Founder of the Current Taxonomic System
Carolus Linnaeus (1707 – 1778)
- Author of Systema Naturae, his
classification system
- Uses binomial nomenclature:
-- each species is assigned 7
names (one for each level
of organization)
-- We usually only say the
last 2 (Genus and Species)

10. Human Versus Squirrel HUMAN SQUIRREL
Kingdom Animalia Animalia
Phylum Chordata Chordata
Class Mammalia Mammalia
Order Primates Rodentia
Family Hominidae Sciuridae
Genus Homo Sciurus
species sapiens carolineus

11. Binomial Nomenclature
Means “2-names”
Homo sapiens
Ex. : Ceanorhabditis elegans or
Ceanorhabditis elegans

13. Kingdom Animalia We will go from simple  complex Body Symmetry
A. Asymmetry
1. You can’t divide into two equal halves
Sponge Amoeba

14. B. Radial Symmetry
1. You can divide it in half in many places
Wheel Starfish
Bilateral Symmetry
1. You can divide it down the middle and
get two mirror images
2. It has a midline

15. Cells  Tissue  Organs  Organ Systems
II. Reproduction
A. Asexual
B. Regeneration
C. Sexual
1. Hermaphrodites – both sexes in one
2. Separate Sexes
III. Development of Organ Systems
A. In order to respond to the environment:
Food, Air, Waste
Cells  Tissue  Organs  Organ Systems
