1. Cell review
Page 3 of the cell packet

2. Significant Scientists
Hooke: first cell observation, looked at dead cork cells
Leewenhoek: with a better light microscope, viewed the first living cell
Schleiden: All plants are made of one or more cells
Schwann: All animals are made of one or more cells
Virchow: All cells come from preexisting cells

3. Cell Theory
All organisms are composed of cells
Cells are the most basic unit of structure
All cells come from preexisting cells

4. Features common to all cells
Cell Membrane
Cytoplasm
Control Center – DNA
Ribosomes

5. Difference Prokaryote (bacteria). -small. -no nucleus
