II. History
   
     A. Antony van Leeuwenhoek (1632-1723)
   
          1. Animalcules
   
     B. Robert Hooke (1635-1703) 
   
          1. Micrographia (1665) 
   
               a. Coined the word "Cells"
   
     C. Matthias Schleiden (1804-1881) &
          Theodor Schwann (1810-1882) 
   
          1. The Cell Theory
   
     D. Rudolf Virchow (1821-1902) 
   
          1. "Omnis cellula a [e] cellula."
   
             "All cells come from
               [preexisting] cells."
   
          2. Spontaneous Generation
   
III. Cells
   
     A. What Are Cells?
   
     B. Organisms
   
          1. Unicellular
   
          2. Multicellular
   
     C. Cytology
   
IV. Types of Cells
   
     A. Prokaryotic Cells
   
          1. Examples

               b. Cyanobacteria
               c. Mycoplasmas
   
          2. Prokaryotic Cells Do Not Have
   
               a. A Nucleus
               b. Many other organelles
   
          3. Prokaryotic Cells Do Have

               a. Everything Else
   
          2. Eukaryotic Cells Have
   
               a. A "True" Nucleus
               b. Extensive Membranes
               c. Many Different Organelles
