1. Prokaryotes vs Eukaryotes Notes

2. Objectives/Why does this matter?
Learning Targets:
Are there different types of cells?
How does the endosymbiotic theory explain a eukaryotes nucleus?
Objective: We will be able to use a Venn Diagram in order identify the key characteristics in eukaryotes and prokaryotes.

3. One way to remember the difference
Eukaryote
Eukaryote has true nucleus
EU = True
Prokaryote
Prokaryote has no nucleus
PRO = No or Before
Kary = Nucleus

4. What are some differences you see between these two cells?

5. Types of Cells Prokaryotes
Archaeabacteria
Eubacteria
Eukaryotes (Protists are a clade of eukaryotes that can mimic the three eukaryotic kingdoms)
Animal
Plant
Fungi

6. What are organelles?
A specialized part of a cell with a specific function 
Mini “organs” of a cell.

7. All Cells (prokaryotic and eukaryotic) have
Have DNA (genetic material)
Have Ribosomes
Are enclosed by a Cell membrane.
Are filled with Cytoplasm.
cell membrane
Bacterium
(colored SEM; magnification 8800x)
cytoplasm

8. Common features of all cells
Cell Membrane
Outer layer that controls what enters & exits the cell

9. Common features of all cells
2. Cytoplasm
Jelly like material which cell organelles float in

10. Common features of all cells
3. DNA- genetic material

11. Common features of all cells
4. Ribosome
– site of protein synthesis

12. Prokaryotes Prokaryotic cells No nucleus No organelles Smaller in size
Simple structure
Unicellular
nucleus
organelles
cell membrane
cytoplasm

13. Eukaryotes Eukaryotic cells Have a nucleus Have organelles
Are larger in size
More complex structure
Multicellular
nucleus
organelles
cell membrane
cytoplasm

14. Nucleus DEFINITION: b. FUNCTION: Control center of the cell
the “brain”
b. FUNCTION:
-Stores all DNA
Nucleus

15. Prokaryotes vs Eukaryotes
Venn Diagram
In your composition book, make a Venn Diagram comparing and contrasting
Prokaryotes vs Eukaryotes

16. Prokaryotes Eukaryotes
Cell Membrane
Cytoplasm
DNA
Ribosomes

17. Prokaryotes Eukaryotes
No Nucleus
No organelles
Smaller in size
Simple
Unicellular organisms
Cell Membrane
Cytoplasm
DNA
Ribosomes
Nucleus present
Has organelles
Bigger in size
More complex
Multicellular organisms
