1. The Six Kingdoms

2. Before we get to the kingdoms…
Prokaryote: An organism whose cells lack a nucleus some other cell structures.
Eukaryote: An organism with cells that contain nuclei and other cell structures.
Heterotroph: An organism that cannot make its own food.
Autotroph: An organism that can make its own food.

3. This is how scientists classify today:
Is it unicellular or multicellular?
Is it a heterotroph or an autotroph?
Is it a prokaryote or a eukaryote?
1 cell
More than 1 cell
Can’t make its own food
Makes its own food
Lacks a nucleus
Has a nucleus

4. Archaebacteria “Ancient Bacteria”.
Already existed on Earth for millions of years before dinosaurs appeared.
Examples: bacteria that live in extremely hot environments.
Classification:
Unicellular
Autotrophs or heterotrophs
Prokaryotes

5. Eubacteria Bacteria that produce yogurt.
Bacteria that give you strep throat.
Classification:
Unicellular
Autotrophs and Heterotrophs
Prokaryotes

6. Protists “odds and ends” kingdom.
Examples: Seaweed, algae, amoeba, paramecium, euglena.
Classification:
Most are unicellular
Autotrophs and Heterotrophs
Eukaryotes

7. Fungi Mushrooms, Mold, and Mildew. Feed on dead or decaying organisms.
Classification:
Multicellular (except yeast)
Heterotrophs
Eukaryotes

8. Plants Without plants life on Earth would not exist. Why?
Plants feed almost all heterotrophs on Earth.
Dandelions in a field, mosses in a forest, and tomatoes in a garden.
Classification:
Multicellular
Heterotrophs
Eukaryotes

9. Animals
Animals have different adaptations that allow them to locate food, capture it, eat it, and digest it.
Classification:
Multicellular
Heterotrophs
Eukaryotes
