1. Classification
Lions, and Tigers, and Bears, and Bacteria, and Archaebacteria, and everything else….Oh my!

2. Classification Click Here for Official Definition
Classification - basic method humans use to organize the living world.
Easy and time-saving
Tells us about organism interrelationships
Allows information to cross language and cultural barriers
Various fields depend on the correct identification of disease-causing organisms and insect pests

3. Types of Classification
smallest
Organisms are grouped into smaller and smaller groups based on their differences and similarities.
largest

4. Domains
Three Domains:
Archaea
Bacteria
Eukarya

5. Domains What’s the difference between the domains?
Eukaryotic cells versus Prokaryotic cells
Domain Eukarya have Eukaryotic cells (Nucleus!)
Domains Archaea and Bacteria have Prokaryotic cells (No Nucleus!)

6. Kingdom Archaebacteria
Kingdoms
Each Domain is broken into Kingdoms.
Kingdom Fungi
Domain Eukarya
Kingdom Plantae
Kingdom Animalia
Kingdom Protista
Domain Bacteria
Kingdom Eubacteria
Domain Archaea
Kingdom Archaebacteria

7. How does classification work?
Life
prokaryotic
eukaryotic…
All prokaryotic organisms are in Domain Archaea or Domain Bacteria
Organisms are divided between them by the slight differences in the organisms’ cell structure.
Ex. Cell walls have peptidoglycan
Ex. Cell walls have no peptidoglycan
Domain Bacteria
Domain Archaea
Kingdom Eubacteria
Kingdom Archaebacteria

8. How does classification work?
Sorting eukaryotic organisms into Kingdoms:
prokaryotic or eukaryotic
unicellular or multicellular
autotrophic or heterotrophic
mode of reproduction

9. Life eukaryotic prokaryotic… Domain Eukarya heterotrophic autotrophic
Not plants, animals, or fungi
heterotrophic
Kingdom Protista
Sexual reproduction
autotrophic
Asexual reproduction
Kingdom Plantae

Unicellular or Multi-cellular
Autotrophic or Heterotrophic
Sexual or Asexual Reproduction
Kingdom Animalia

10. So now what? Now it’s your turn! Break into pairs.
Each pair send up a representative to collect a plastic organism bag and a Kingdom Answer Key.
When you return to your desk, WRITE YOUR NAMES on the Kingdom Answer Key.
