2. Mor-ganelles  What is the BIG difference between prokaryotic and eukaryotic cells?  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. FIRST FIVE.

3. Agenda  Catalyst  Energy Organelles  Energy Organelles Challenge  Independent Practice  EQ

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

5. REMEMBER:  Organelles are the small parts of a cell  We have already learned about…  Nucleus  Cytoplasm  Cell membrane

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

7. Mitochondria

8. Write – Pair – Share Create an analogy: If IMCS was a cell, what would be the mitochondrion?

9. 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

10. Chloroplast

11. Write – Pair – Share Create an analogy: If IMCS was a cell, what would be the chloroplast?

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

13. VACUOLE

14. Write – Pair – Share Create an analogy: If IMCS was a cell, what would be the vacuole?

15. 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

16. PLANT CELLS

17. ANIMAL CELLS

18. Double Bubble (In your notes) Plant Cell Animal Cell

20. Organelle Showdown DIRECTIONS:  Quiz your partner (using flash cards)  Ask difficult questions!  Keep track of points  First student to earn 15 points wins  I want to know who is the organelle master in each pair! REMEMBER OUR OBJECTIVES:  Describe the structure and function of cell organelles related to energy  Determine if a eukaryotic cell is a plant or an animal

21. Whiteboard Practice  Please send someone up from your group to grab…  One whiteboard for each person  One dry-erase marker for each person  Two erasers for your group  Behavioral expectations  Take the work seriously  Stay focused and on task

22. What is the function of the nucleus?

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

24. This organelle is MUCH larger in plants than animals

25. What is the function of the mitochondria?

26. (throwback!) These types of cells do not have a nucleus

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

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

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

30. Which of these cells is a plant cell? OPTIONSEXPLAIN HOW YOU KNOW THIS IS OR IS NOT 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

31. (throwback!) Using your knowledge of the characteristics of life, explain why the parts of cells are alive or not alive.

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

35. Plant cell or animal cell? How do you know?

37. Independent Practice  Begin on the worksheet.  Now is the time to ask questions! Not during the quiz!  What you do not complete is homework.

38. Exit Questions 1. Compare plant and animal cells. (Identify at least three differences.) 2. Describe the function of the chloroplasts. 3. Which organelle produces ATP? Complete sentences! Don’t talk!
