3. Kingdom Archaebacteria
-Unicellular Archaebacteria – no peptidoglycan
- Prokaryotic unique cell walls
- Autotrophic and Heterotrophic
Found in extreme environments
such as Salt lakes, Deep Oceans, and
Hot Springs exceeding 100 degrees C.
Some may live in an Oxygen-free environment

4. Kingdom eubacteria Eubacteria – all other bacteria
-complex internal structures
-Prokaryotic
-Cell wall with peptidoglycan
-Most abundant organism on Earth
-Unicellular
-Autotrophs and Heterotrophs

5. Kingdom protista Protista -Eukaryotic -Unicellular and multicellular
-Some species with cell walls
-Autotrophic and Heterotrophic

6. Kingdom Fungi Fungi: -Eukaryotic -cell walls with chitin
-mostly multicellular
(may be unicellular)
-Heterotrophs

7. Kingdom Plantae Plantae – -Eukaryotic -Multicellular
-Autotrophs (Makes its own food)

9. Review: 1. How many Domains (super kingdoms)? 2. How many Kingdoms?
3. Which kingdom do you belong to?
4. What is a heterotroph?
5. What is an autotroph?
6. How is a Prokaryotic organism different from an Eukaryotic
organism?

10. Answers to Review: 1. 3 domains 2. 6 kingdoms 3. Animal kingdom
4. Heterotroph cannot make its own food
5. Autotrophs can make their own food
6. Prokaryotic organisms do not have a nucleus or
membrane bound organelles.
