3. Essential Question Standard
How can I compare prokaryotic and eukaryotic cells
Standard
B.4A – Compare and contrast prokaryotic and eukaryotic cells

4. Prokaryote: Eukaryote:
Alive (8 characteristics), DNA, RNA, Cytoplasm, Ribosomes,
Cell Membrane, Microscopic
*Cell Wall
Make sure you get this info…
Prokaryote:
Eukaryote:
Lacks Nucleus
Organelles Lack Membranes
DNA is free floating
Always unicellular
Always bacteria
Smaller than Eukaryote
Reproduction is asexual (exact copies/clones)
Has Nucleus
Organelles have Membranes
DNA is in the Nucleus
Can be unicellular or multicellular
Plants, Animals, Fungi, Protists
Much Larger than Prokaryote
Reproduction can be asexual (clones) or sexual (variations)

Title: Endosymbiotic Theory
Essential Question:
What does the Endosymbiotic Theory attempt to explain?

6. There are many theories about how the first Eukaryotes emerged.
The Endosymbiotic Theory states that the organelles of eukaryotes originated as a symbiosis between separate single-celled prokaryotes.

7. Break it down…. Endo = inside Symbiosis = a beneficial relationship
Fat Tony:
Endo. Theory with Playdoh:

8. Endosymbiotic Theory Prokaryotic Cell #1 NEW Eukaryotic Cell Cell #2
Cell #2 (mitochondria)
Cell #2
(chloroplast)
NEW Eukaryotic Cell

9. Explains how organelles were most likely formed
Also explains why organelles are membrane-bound

10. Cell Organelles and their Functions

11. New Topic/Page
Page___
Title: Organelles
How do organelles help the cell maintain homeostasis?

12. Two Types of Cells
EUKARYOTE
PROKARYOTE

13. Cell Diagrams -Number the boxes going horizontal
Front Side – Color what the arrows are pointing to
Back Side – Label

14. Left side– Cell Diagrams
Nucleolus
Cytoplasm
Rough ER
Ribosome
Cell Membrane
Mitochondria
Lysosome
Smooth ER
Golgi Bodies (Apparatus)
Vacuole
Flagella
Nucleus

15. Nucleolus
Largest structure inside the nucleus
Ribosome synthesis 1.

16. Rough Endoplasmic Reticulum
A network of membranes throughout the cytoplasm of the cell.
Aids in assembly of ribosomes. 2.

17. 3. Cell Membrane The cell membrane holds the cell together
Semi-permeable
Allows substances into and out of the cell. 3.

18. Lysosome
act as the waste disposal system of the cell by digesting unwanted materials 4.

19. Golgi apparatus
Responsible for sorting, packaging, and shipping the proteins produced in the ER. 5.

20. 6. Nucleus The nucleus controls the cell.
It contains the cell’s DNA (genetic info and instructions for making proteins) 6.

21. Cytoplasm
the watery gel inside a cell.
It holds the ORGANelles. 7.

22. 8. Ribosomes Play an important role in the synthesis of proteins.
Some ribosomes are found in the cytoplasm, but most are attached to the endoplasmic reticulum.
Found in both Eukaryotes and Prokaryotes 8.

23. 9. Mitochondria Organelle that produces energy for the cell.
The “power house” 9.

24. Smooth Endoplasmic Reticulum
A network of membranes throughout the cytoplasm of the cell.
It helps to move materials around the cell.
10.

25. Vacuoles
Vacuoles are spaces in the cytoplasm where food, water and chemicals are stored
11.

26. 12. Flagella Can be found in both prokaryotic and eukaryotic cells
Used for movement
12.

27. 13. Cell Wall They make the cell strong and rigid-support
Cell Walls are found plants, fungi, bacteria and some protists
NEVER found in animal cells
13.
