1. Kingdoms

2. Domain Archaea Corresponds to kingdom Archaebacteria
Prokaryotic and unicellular organisms
Autotrophic & Heterotrophic
No organ systems
Example: E-coli
Cell walls lack peptidoglycan, cell membranes contain unusual lipids not found in any other organism.
Live in extreme environments (volcanic hot springs, black organic mud, salt marshes)

3. Domain Bacteria Corresponds to the kingdom Eubacteria
Unicellular and prokaryotic organisms
Autotrophic & Heterotrophic
No organ systems
Example: Streptococcus (strep throat)
Thick, rigid cell walls

4. Domain Eukarya All organisms have a nucleus
Composed of the four remaining kingdoms:
Protista
Fungi
Plantae
Animalia

5. Kingdom Protista

6. Kingdom Protista
Eukaryotic organisms that cannot be classified as plants, animals, or fungi.
Unicellular & some multicellular algae
Autotrophs & heterotrophs
No complex organ system
Examples: Plasmodium (causes malaria), amoeba, paramecium, kelp, slime mold…
Greatest variety
Known as “catch all group”

7. Kingdom Fungi Eukaryotic
Most are multicellular (mushrooms), yet some fungi, such as yeasts, are unicellular
Heterotrophic: feed on dead or decaying organic matter (decomposers)
They secrete digestive enzymes into their food source. Then they absorb the smaller food molecules into their bodies.
Reproductive structures
Examples: mushrooms

8. Kingdom Plantae Eukaryotic Multicellular Photosynthetic: autotrophs
Non-motile, but contain organ systems
Cell walls made of cellulose
Examples: includes cone-bearing and flowering plants, mosses, and ferns

9. Kingdom Animalia Eukaryotic Multicellular Heterotrophic
Complex organ systems
Examples: Mammals, birds, reptiles, fish, insects…
Lack cell walls, most can move, very diverse
