3. Do Now 8/17/15 All living things are composed of what?
What is the difference between unicellular and multicellular organisms?
List any information that you already know about cells.

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

5. Cell Facts
The average human being is composed of over 50 Trillion individual cells!!!
It would take as many as 50 cells to cover the area of a dot on the letter “i”
WOW!!!

6. Principal # 1
The cell is the most basic unit of life.

7. Principal # 2 All organisms are made of one or more cells.
(Think- unicellular vs. multicellular)

8. Principal # 3
All cells are produced by pre-existing cells.

9. Types of Cells
Prokaryotic
Eukaryotic

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

11. All Cells… (Both Prokaryotic & Eukaryotic)
Are enclosed by a cell membrane.
Are filled with cytoplasm.
Have ribosomes
Have DNA (genetic material)
cell membrane
Bacterium
(colored SEM; magnification 8800x)
cytoplasm

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

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

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

15. Prokaryotes Eukaryotes
Fill in the left and right parts of the diagram with your shoulder partner
(must have 4 to 5 traits listed for each)
Prokaryotes Eukaryotes

16. 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

17. Assignment Work on handout independently We are on CODE RED
