1. Classification
The Five Kingdoms

2. Aristotle

3. Aristotle First scientist recognized for classifying organisms.
Aristotle’s system was used from around 300 BC until the 1600’s.
That is about 2000 years!

4. Fly Plants Animals All Living things With Blood Without Blood Swim
Walk
Fly

5. What about the Duck?

6. Carolus Linnaeus

7. Linnaeus Scientist in the 1700’s
Classified organisms based on similarities in their structure!
2 Kingdoms: Plants and Animals
Why not other kingdoms, like bacteria?
Split kingdoms into groups called genera (genus)
Divided each genus into multiple species

8. Each organism had many common names, so each species has a two-part scientific name:
1st name: genus 2nd name: species
Example:
Ursus americanus
Ursus arctos
Ursus maritimus

9. Binomial Nomenclature = 2 name naming system
Two parts to every name:
Baleonoptera musculus
(Genus) (Species)

11. Example
Kingdom: Plants Phylum: Vascular plants, seed bearing Class: Pinopsida Order: Pinales (conifers) Family: Pinaceae (Pine) Genus: Picea (Spruce) Species: Picea pungens (Blue Spruce)

12. Example
Kingdom: Animals Phylum: Chordata Class: Mammalia Order: Primates Family: Hominidae (gorillas, orangutans, humans) Genus: Pan Species: Pan troglodytes (Chimpanzee)

13. Example
Kingdom: Animals Phylum: Chordata Class: Mammalia Infraclass: Marsupialia (pouch) Order: Diprotodontia (two forward teeth) Family: Phascolarctidae Genus: Phascolarctos (pouch & bear) Species: Phascolarctos cinereus (Koala)

15. Eukaryote: Organism whose cells have a true nucleus
Prokaryote: Organism whose cells do not have a true nucleus
Heterotroph: Organism that cannot make its own food, it must get food from another source
Autotroph: Organism that can make its own food

16. Kingdom Monera Unicellular Cell has no true nucleus No cell wall
Some make their own energy, some don’t
Examples: Bacteria

17. Kingdom Protista Unicellular Have a nucleus No Cell Wall
Some make their own energy, some don’t
Examples: Amoebas, Diatoms, Paramecium

18. Kingdom Fungi Multi-cellular Have a nucleus
Have cell walls with chitin
Can’t make their own energy
Examples: Mushrooms, Mold, Yeast

19. Kingdom Plant Multi-cellular Have a nucleus
Have a cell wall with cellulose
Make their own energy (photosynthesis)
Examples: Algae, Mosses, Ferns, Flowering Plants, Flowering Trees, Conifers

20. Kingdom Animal Multi-cellular Have a nucleus No cell wall
Can’t make their own food
Examples: Sponge, Jellyfish, Insects, Frog
