1. Prokaryotes vs Eukaryotes

2. Cells Prokaryotes Eukaryotes Bacteria Fungi Protists Archaea Plant
Animal

3. Cell History Prokaryotic Eukaryotic Ancient cells First type of cell
Primitive cells
Modern cells

4. Two Cell Types
Prokaryotic
Eukaryotic

5. Prokaryotic Cells
Pili

6. Prokaryotic Cells No membrane bound nucleus
Nucleoid = region of DNA concentration
Organelles not bound by membranes

7. Eukaryotic Cells Nucleus bound by membrane
Include fungi, protists, plant, and animal cells
Possess many organelles
Protozoan

8. Flagellum Pili Capsule Cell Wall Plasma Membrane Ribosomes DNA
Structure Functions
Draw a bacteria cell and label the following parts and describe the function:
Flagellum
Pili
Capsule
Cell Wall
Plasma Membrane
Ribosomes
DNA

9. Flagellum
Hair-like structure
Used for locomotion  movement

10. Pili Tiny hair-like structures that branch out from cell wall
Attach to host tissue or cell  gives them the ability to cause infection
Used for conjugation (sending genes)

11. Capsule Protects from drying out
provides protection against phagocytosis from immune cells

12. Cell Wall Makes cell rigid and gives it shape
An anchor for pili and flagella

14. Cell Size

15. Cell Size Prokaryotic Eukaryotic Smaller cells 1 to 10 µm Larger cells

16. Cell Size Comparison

17. Cell Organization Prokaryotic Eukaryotic
Simple cells with all parts in “one room”
Complex cells with many compartments

18. Presence of Organelles
Prokaryotic
Eukaryotic
Ribosomes only
Many, specialized organelles

19. Nucleus
Prokaryotic
Eukaryotic
NONE!
Present

20. DNA Prokaryotic Eukaryotic DNA is loose in the cytoplasm
DNA held of circular chromosome
DNA is protected in the nucleus bound by a membrane
DNA held on linear chromosomes

21. Ribosomes
Prokaryotic
Eukaryotic
Small (70s)
Large (80s)

22. ATP Prokaryotic Eukaryotic
Production occurs in infolded regions of the cell surface membrane called mesosomes
Production occurs in mitochondria

23. Cell Wall Prokaryotic Eukaryotic Peptidoglyan based (if present)
Cellulose based (if present)

24. Type of Organisms Prokaryotic Eukaryotic Bacteria only!
Plants, Animals, Fungi, and Protists
Archaea

25. Size of Organisms Prokaryotic Eukaryotic Always unicellular
Bacteria are cell size: 1 to 10 µm
Eukaryotic
Mostly multi-cellular
Range from cell size (10µm) to the size of a sequoia tree (83 m)
