Early Microscopes-Robert Hooke (cork)-
Van Leeuwenhoek(pond water)
Scientists: Schleiden (plants), Schwann(animals) & Virchow(new from existing)
Key A:The Cell Theory
All living have cells

Microscope Types
Light Microscope
Electron Microscopes
TEM (Transmission Electron)-beams electrons pass through.
SEM (Scanning Electron)-electrons pass over.

3. Prokaryotes(Pro, No nucleus) Eukaryotes
Key Q: How are prokaryotic & eukaryotic cells different?
Prokaryotes(Pro, No nucleus) Eukaryotes
No nucleus to separate the genetic material from the rest of the cell.
Yes nucleus to separate the genetic material from the rest of the cell.

4. Cell Membrane- thin flexible barrier that surrounds all cells; regulates what enters & leaves.
Nucleus-controls the cell; contains DNA.
Key A:Prokaryotic cells do not separate their genetic material within a nucleus.
Key A: Eukaryotic cell, the nucleus separates the genetic material from the rest of the cell.
