3. Essential Question Agenda 10/18 Learning Goal
How do cells function to make up living things?
Review Discovery of cells/Cell Theory
HW: Create a poster displaying the 3 parts of the cell theory
Learning Goal
Explain how the cell theory changed over time
Compare the compound light microscope to the dissecting scope.
Identify the differences between prokaryotes & eukaryotes.
Identify the differences between plant & animal cells.

4. Discovery of the Cell Theory
You will have about 20 minutes to Read section 3.1 in your text book. WRITE what each person did to contribute to discovering cells then, DRAW and COLOR a picture in each pane to represent what the scientists discovered.

5. Robert Hooke Viewed cork
Named what he saw cells to resemble the jail cells

6. Anton van Leeuwenhoek Made better more powerful lenses for microscope
Observed cells in greater detail
1st to view living things

7. Turn and Talk – Shoulder Partners
When doing turn and talks these are quick!
They should not take more than seconds MAX.
If you don’t know the answer, read off your notes. Then put your notes down and say it again without looking.
Partners, make sure no one says the word “IT”! All students must use proper terminology to learn the material.
Correct each other if mistakes are made.
When finished with the question STOP TALKING and LOOK at the teacher.

8. Turn and Talk – shoulder partners
High five your shoulder partner
Determine who is Partner A and who is Partner B
Partner A turn to Partner B and Explain what Robert Hooke did to contribute to the cell theory
Partner B turn to Partner A and Explain what Anton Van Leeuwenhoek did to contribute to the cell theory
Robert Hooked looked a cork under a microscope and decided to name what he saw cells after the jails cells
Anton Van Leeuwenhoek made a higher power microscope and was the first person to view a living cell

9. Mathias Schleiden 1st to study plants Stated plants made of cells
Called friends to share information

10. Theodor Schwann Noticed plants and animals had similarities
Concluded all living things are made of cells

11. Rudolf Virchow
Stated cells come from preexisiting cells NOT from spontaneous (random) generation

12. Turn and Talk – face partners
High five your face partner
Determine who is Partner A and who is Partner B
Partner B turn to Partner A and Explain how Schleiden and Schwann contributed to the cell theory
Partner A turn to Partner B and explain What did Rudolf Virchow do that was SO important for the cell theory?
Schleiden studies plants and realized they were made of cells so he called his friend Schwann who was studying animals and realized they were made of cells too!
Virchow is important because he realized that cells come from preexisting cells and that radically changed the idea of the time that they were created randomly

13. So what is the Cell Theory
All organisms are made of _________
All existing cells are produced by other living _______
The ______ is the most basic unit of life
Watch the following video and add to your notes!
CELLS
CELLS
CELL

14. Exit ticket Answer the following question IN COMPLETE SENTENCES:
How has the cell theory changed over time? Include people and what they did to contribute to the final theory.
Write down any question you have from today’s lesson.
Reminder: HW-cell theory poster due tomorrow!

18. Cell Theory Review
What does the cell theory say is true about a sea turtle and pine tree?
Both are made of one or more cells
Both have the same # of cells
Both have tissues
Both have the same type of cells

19. Cell Theory Review

20. Essential Question Agenda 10/19-20 Learning Goal
How do cells function to make up living things?
Prokaryote vs. Eukaryote Video/Reading
HW: Study over material covered this week to prepare for a quiz next week!
Learning Goal
Explain how the cell theory changed over time
Compare the compound light microscope to the dissecting scope.
Identify the differences between prokaryotes & eukaryotes.
Identify the differences between plant & animal cells.

21. Main Types of Cells
You have 10 minutes to Read page 73 and complete the Venn Diagram

22. Now watch the video and add to your notes 2 main types of cells: Prokaryotic and Eukaryotic

23. 2 main types of cells: Prokaryotic and Eukaryotic
Does NOT have a nucleus or membrane bound organelles
Single celled organism
Has a nucleus and membrane-bound organelles
Multicellular organisms
Microscopic in size
Enclosed in a membrane
Contain cytoplasm
Contain organelles
RIBOSOMES

24. QUICK WRITE – 2 minutes
Using what you have learned in class and given the following picture, identify each image as a prokaryote or eukaryote and explain why! Be specific and use and underline terms.
Figure A
Figure B

25. Share out Switch papers at your table Read what your tablemate wrote
Write whether you agree or disagree with their response and WHY. BE SPECIFIC!

26. What do we think? Check yourself
Figure A
Figure B
Figure A is a Eukaryotic cell because it has more organelles inside and is very complex. It also has only one cell boundary, a cell membrane
Figure B is a Prokaryotic cell because it is much simpler than Figure B. There are not a lot of organelles inside of it and it has two boundaries around the cell, a cell wall and a cell membrane.
