2. B.4A – Compare and contrast prokaryotic and eukaryotic cells
Standard
B.4A – Compare and contrast prokaryotic and eukaryotic cells
Essential Question
What are the defining characteristics of prokaryotic cells?

3. Card Sort…
Number off… Station assignments… Time Limit

4. Cell Theory Article Partner A Read Partner B Listen
Both Partners discuss and summarize the KEY POINTS of each paragraph.
Partners switch roles with each paragraph.

5. Cell Theory All living things are made up of cells
Cells are the smallest units of life
All cells arise from other preexisting cells

6. Can you recall the three components of cell theory without looking at your notes?

7. Standard B4.A:
Compare and Contrast prokaryotic and eukaryotic cells

8. Cell Types…. Take a look at the pictures
Partners compare/contrast the two
What are the similarities
What are the differences

9. In Biology, cells are the building blocks for every form of life
In Biology, cells are the building blocks for every form of life. All cells are classified into one of two categories…
Prokaryotes (prokaryotic cells) or
Eukaryotes (eukaryotic cells)
And that is it!

10. Today we will focus primarily on the Prokaryotes
What is a prokaryote?

12. Prokaryotes: Prokaryotes are unicellular microorganisms
Prokaryotes are bacteria!
All Bacteria are prokaryotes!
These cells lack (do not have) a distinct nucleus
These cells lack (do not have) organelles surrounded by membranes
These cells are extremely simple and small
“Pro Means
No!!!”
Say It!
Lack = does not have
Micro = really small
Bound = surrounded by
Membrane = thin outer covering
Organelles = tiny organs

13. Due to their simplicity, prokaryotes are believed by scientists to have been the earliest forms of life on the planet.
They may have lived earlier than 3.77 billion years ago, possibly as early as 4.28 billion years ago, not long after the oceans formed 4.41 billion years ago, and not long after the formation of the Earth billion years ago.
Bacteria (prokaryotes) are a very diverse group! They can live in the most extreme environments and very common ones as well. There are literally billions of bacteria living on/in you right now!

14. Prokaryotes:
Say It!
“Pro
Means
No!!!”

15. “Pro Means No!!!” Prokaryote Structures you need to know: Say It!
Cell Wall: all prokaryotes/bacteria have a cell wall. Provides support. Material can be different depending on species.
Cell Membrane: adds additional support, controls what enters/leaves the cell.
Cytoplasm: gel like substance that contains the structures of the cell
Ribosomes: responsible for the synthesis of essential proteins/enzymes
Flagellum: used for transportation through liquid based environments
Nucleoid: Circular free floating DNA, not surrounded by a membrane
Say It!
“Pro
Means
No!!!”

16. Prokaryotes are much smaller than Eukaryotes
Prokaryote (Bacteria)
Eukaryote (Animal Cell)

17. Structure determines…function!! Adaptations etc.

19. Odd One Out- In 50 words or more describe which image is the odd one out and why.
