1. Chapter 3
Cell Structure

2. Chapter 3C
Types of Cells

3. III. Types of Cells All cells fall into one of two major categories:
A. Eukaryotic cells
B. Prokaryotic cells

4. A. Eukaryotic Cells Have a “true nucleus” with a nuclear membrane
2. Cells in humans, animals, plants, fungi, algae, and protozoans

5. A. Eukaryotic Cells
3. Contain all or most types of organelles

6. B. Prokaryotic Cells No nuclear membrane
* Nucleoid region instead
2. Contain only organelles that are not surrounded by a membrane
3. Bacteria cells

7. Diversity Among Eukaryotes
Eukaryotic cells have much variety
Cilia and flagella
Chloroplasts
Vacuoles
Cell walls

8. What are the differences & similarities?

9. Irreducible Complexity
Proposed by Michael Behe in his book, Darwin’s Black Box
The parts of a cell are so dependent on one another that if just one part does not work right, the entire cell would most likely die.

10. Irreducible Complexity
The cell cannot be reduced to something less complex and still function properly.
Irreducible complexity points to a Designer of the cell and of the universe.
