2. Mor-ganelles  Catalyst:  What can plants do that animals can’t?  What is the function of the cell membrane?  If a cell’s nucleus is destroyed, the cell immediately dies. Using the function of the nucleus, explain why. Write in complete sentences! Don’t talk during the Catalyst!

3. Objectives  By the end of today, SWBAT…  Describe the structure and function of cell organelles related to energy  Determine if a eukaryotic cell is a plant or an animal

4. Mitochondria  The mitochondria are oval shaped and have lines through them  They produce energy (ATP) for the cell

5. Mitochondria

6. Think-Pair-Share If West Jeff were a cell, what would be the mitochondrion?

7. Chloroplast  Chloroplasts are green ovals, and look like they contains stacks of poker chips  They allow plants to photosynthesize (use sunlight to make sugar)  Only found in plant cells

8. Chloroplast

9. Think-Pair-Share If West Jeff were a cell, what would be the chloroplast?

10. Vacuole  Circular storage space for food and water  In plant cells, it is gigantic

11. VACUOLE

12. Think-Pair-Share If West Jeff were a cell, what would be the vacuole?

13. Cell Wall  The cell wall is found outside the cell membrane in plant cells  It holds plant cells in a rectangular shape  Only found in plant cells

14. PLANT CELLS

15. ANIMAL CELLS

16. Think-Pair-Share If West Jeff were a cell, what would be the cell wall?

18. Organelle Showdown  Choose a partner at your table, and (using the flash cards) quiz him/her  Ask difficult questions!  Keep track of points  First student to earn 20 points wins  I want to know who is the organelle master at each table!

19. Whiteboard Practice  Please send someone up from your group to grab…  One whiteboard for each person  One dry-erase marker for each person  Behavioral expectations  Take the work seriously

20. What is the function of the nucleus?

21. What two organelles that we discussed today are only found in plant cells?

22. This organelle is MUCH larger in plants than animals

23. What is the function of the mitochondria?

24. These types of cells do not have a nucleus

25. Both the chloroplast and mitochondria make energy, but different types. What do each of them produce?

26. What would happen to a cell, if its vacuole were destroyed?

27. This part of the cell is the reason why plants are rectangular in shape

28. Which of these cells is a plant cell?  Cell #1: cell membrane, nucleus, cytoplasm, vacuole  Cell #2: cell wall, cell membrane, nucleus, chloroplast, cytoplasm  Cell #3: cell membrane, cytoplasm, DNA floating in cytoplasm  Cell #4: cell membrane, nucleus, cytoplasm, mitochondria, vacuole

29. Which organelle is this arrow pointing to? What is its function?

32. Plant cell or animal cell?

34. Independent Practice  Begin on the homework

35. Exit Questions  Describe at least TWO differences between plant and animal cells  What is the function of the chloroplasts?  Which organelle produces ATP? Write in complete sentences! Don’t talk during the Exit Question!
