CHAPTER 1: INTRODUCTION TO CELL
BIOLOGY
1. Cell Theory: Created by Schlseiden, Schwann, and Virchow.
1) All living organisms are composed of cells
2) Cells are the functional and structural unit of life
3) Cells are the simplest unit of life
4) All cells arise from pre-existing cells
2. Cells with Nucleus: Eukaryotic
3. Cells without Nucleus: Prokaryotic
4. Cell Unity (All cells exhibit these characteristics): 1) Store genetic information as
DNA
2) Replicate DNA by template polymerization
3) Transcribe genetic information into RNA
4) Translate RNA into proteins
5) Use protein catalysis
6) Regulate genes
7) Require free energy
8) Synthesize biological macromolecules from subunits
9) Enclosed in a plasma membrane
5. Prokaryotic Cell Structure: - Bacteria and Archaea
