Things to find out about cells
1. What shape do most cells have?
2. How many nuclear membrane layers? Why?
3. What produces energy in a cell?
4. How does water get into a cell?
5. How does CO2 get out of a cell?
6. What does a nucleus do?
7. What does the endoplasmic reticulum do? Look like?

Cell history
• Leeuenhoek
• Hooke
• Schwann
• Schleidan
Contempories; 1730’s
German sci; credited w/ the idea of cell theory; the beg of the end of spontaneous generation

Two Types of Cells
• Prokaryotic• “simple”• no nucleus or
membrane bound organelles
• most have cell wall• All are bacteria of
some type
• Eukaryotic• Have nucleus* and
membrane bound organelles
• More diverse• Only plant and fungi
have cell walls
