1 Prokaryotes vs Eukaryotes

2 Cells Prokaryotes Eukaryotes Plant Animal ProtistsFungi Bacteria Archaea

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

4 Two Cell Types ProkaryoticEukaryotic

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

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 AttributesProkaryotesEukaryotes Cell Size Cell Organization Presence of Organelles Nucleus DNA Ribosomes ATP Cell Wall Type of Organisms Size of Organisms

14 Cell Size

15 Prokaryotic Smaller cells 1 to 10 µm Eukaryotic Larger cells 10 to 100 µm

16 Cell Size Comparison

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

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

19 Nucleus Prokaryotic NONE! Eukaryotic Present

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

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

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

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

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

25 Size of Organisms Prokaryotic 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
