1. Complete Do Now Silently & Independently
Follow the entrance procedure.
Have your homework in the top right corner to be check
Begin working on your Do Now Silently

2. DO NOW- Silently & Independently
1. What are the three principles of cell theory?
2. What did you find out with your research?
**have homework out on your desk to be checked**

3. Objectives/Why does this matter?
EQ: are there different types of cells?
Objective: We will be able to use a Venn Diagram in order identify the key organelles and in eukaryotes and prokaryotes.

4. Agenda Do Now Updates INM: Eukaryotic vs. Prokaryotic
Practice: Venn Diagram

5. Updates
Mid unit exam 1 covering cell theory, prokaryotes, and eukaryotes
Binder set up will occur next time because we still have people without binders.

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

7. Types of Cells
Prokaryotes
Eukaryotes

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

9. All Cells - Are enclosed by a cell membrane.
Are filled with cytoplasm.
Have ribosomes
Have DNA (genetic material)
cell membrane
Bacterium
(colored SEM; magnification 8800x)
cytoplasm

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

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

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

13. Common features of all cells
4. Ribosomes
– site of protein synthesis

14. Prokaryotes Eukaryotes
Fill in the middle part of the diagram with your partner. 1 minute silently and independently (must have at least 4 traits listed)
Prokaryotes Eukaryotes

15. Prokaryotes Eukaryotes
Cell Membrane
Cytoplasm
DNA
Ribosomes

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

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

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

19. One way to remember the difference
Eukaryote
Eukaryote has true nucleus
EU has TRUE
Prokaryote
Prokaryote has no nucleus
PRO has NO

20. Prokaryotes Eukaryotes
Fill in the left and right parts of the diagram with your partner using a volume 1 voice.
(must have at least 5 traits listed for each)
Prokaryotes Eukaryotes

21. 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
