Nucleus, Mitochondrion, Plasma membrane, Ribosomes
2.  Name 2 differences between plant and animal cells.
3. What are membrane-bound structures in eukaryotic cells with specialized functions called?
4. Name 2 characteristics of prokaryotes.
5. Name a kingdom in which the members are eukaryotes. 
6. If you put a piece of lettuce in a dish of saltwater, what will happen to the lettuce cells?
7. What is the function of the plasma membrane?
8. Give an everyday example of passive transport.
9. What process does the decrease in surface area to volume ratio cause to slow down so much that the cell can’t function?

4. SWBAT Scale
4: Same as a 3.0 but I can make inferences & application to the SWBAT’s
3: I COMPLETELY understand all parts of the SWBAT
2: I understand MOST of the SWBAT’s with teacher help
1: I understand a little of the SWBAT’s but need teacher help
0: I do NOT understand any part of the SWBAT’s and need help!

5. Video
Before you go through these notes, watch the following video to preview The Discovery of Cells.
The Discovery of Cells

6. Cell Theory 1665 - Robert Hooke observed cork under microscope
called little boxes he saw “cells”

7. Cell Theory Anton van Leeuwenhoek
discovered organisms too small to see with the naked eye
(his microscope had only one lens)

8. With making of compound microscopes:
Schleiden - observed all plants are made of cells
Schwann - observed all animals are made of cells

9. Schleiden, Schwann, and Virchow contributed to cell theory which states:
1. all organisms are composed of one of more cells
2. the cell is the basic unit of organization of organisms
3. all cells come from pre-existing cells

10. Studying Cells 1. Light microscopes
magnify and focus light reflecting off or passing through specimens
limited to about 2500x magnification

12. Studying Cells 2. Electron Microscopes
passes electrons over or through an object to form a magnified image
focused by electromagnets
image is captured on screen or photographic film

13. Types of Electron Microscopes
Transmission Electron Microscope (TEM)
passes beam of electrons through object (2D)
Scanning Electron Microscope (SEM)
bounces electrons off the surface of object (3D)

14. Cell Types Eukaryote: Has a nucleus Prokaryote: Lacks nucleus
Ex. Animal & plant cells
Prokaryote:
Lacks nucleus
Ex. bacteria
