1 Prokaryotes vs Eukaryotes

2 Cells Prokaryotes Eukaryotes Bacteria Fungi Protists Archaea Plant

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

13 Comparison Chart Attributes Prokaryotes Eukaryotes Cell Size
Cell Organization Presence of Organelles Nucleus DNA Ribosomes ATP Cell Wall Type of Organisms Size of Organisms

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)

26 Representative Animal Cell

27 Representative Plant Cell
