This document discusses the basic types of cells - prokaryotic and eukaryotic cells. It provides definitions for the terms prokaryote and eukaryote based on their Greek roots and describes some key differences between the two types of cells. Specifically, it notes that prokaryotic cells lack a true nucleus and membrane-bound organelles, while eukaryotic cells have a true nucleus surrounded by a membrane and also contain membrane-bound organelles. The document encourages comparing and contrasting the similarities and differences between prokaryotic and eukaryotic cells using a double bubble map.

2. History Review
• Take a minute to remember how the cell
theory came to be. Many different
scientists worked separately, but when
their information was put together, it was
enough to form the Cell Theory.

3. Two Basic Types of Cells

4. What the words mean:
Prokaryotes Eukaryotes
• Pro = before • Eu = true
• Karyose = kernel, which • Karyose = kernel, the
represents the nucleus nucleus
• So prokaryotes are the • So eukaryotes are the
cells without a true cells with a true nucleus

7. Compare and Contrast
• Your turn: What is similar and what is
different about Prokaryotic cells and
Eukaryotic cells?
