1. Review February Valentines Day-10, 2010  What is the function of the endoplasmic reticulum?  What is the function of the ribosome?  Draw a cell in a hypertonic solution and explain what would happen.  How is active transport different than passive transport?

2. Objectives  By the end of today, SWBAT…  Be ready to ace the unit test tomorrow!!!

3. Agenda  CATALYST!  EGG LAB!  ORGANELLE SHOWDOWN!  TRANSPORT TRASHKETBALL!  REVIEW GUIDE WORK TIME!  EXIT QUESTION!

4. Egg Lab!  An egg is ONE cell!  Underneath the shell is a semi-permeable membrane… a cell membrane!  If we put this egg into a hypertonic/hypotonic solution, osmosis will occur.

5. ORGANELLE SHOWDOWN RULES!  Two teams will line up at the board.  Each player has to answer the question as quickly as possible.  Bring your notecards to line to review as we play.  We will keep points and the team with the most points wins!  NO HELPING! Automatic 2 point deduction.

6. SHOWDOWN! This part of the cell is selectively permeable and only allows in certain things.

7. SHOWDOWN! This is an organelle that is found both in prokaryotic and eukaryotic cells.

8. SHOWDOWN! This is an organelle that is found only in plant cells.

9. SHOWDOWN! All organelles are found floating here

10. SHOWDOWN! This organelle allows sunlight to be converted into sugar.

11. SHOWDOWN! This organelle is a pathway for proteins to reach the Golgi apparatus.

12. SHOWDOWN! If this organelle were destroyed, then a cell could no longer create ATP (energy)

13. SHOWDOWN! This organelle packages and ships proteins.

14. SHOWDOWN! In prokaryotic cells, DNA is found floating here

15. SHOWDOWN! This organelle destroys old organelles and cleans up the cell.

16. SHOWDOWN! This organelle is the reason that plant cells are rectangular

17. SHOWDOWN! This organelle contains the instructions for creating proteins

18. SHOWDOWN! Food and water is stored inside of this organelle

19. SHOWDOWN! 2 part question!! 1) Rough ER has this on it. 2) What is the function of the organelle in number 1?

20. SHOWDOWN! 2 PART QUESTION!!! 1) This organelle is much bigger in plants than animals 2) What is the function of the answer to #1?

21. BONUS ROUND! Each question is worth 2 points!!

22. Which of the following is true?  A produces energy for the cell  D holds the DNA only in Eukaryotes  C produces energy for the cell  B is a pathway for proteins to travel

23. Which of the following is FALSE?  (1) holds DNA in eukaryotic cells  (3) holds food and waste and is huge in plant cells  (4) is only present in animal cell  This is a plant cell

24. Transport rules- Remember these to be golden  A) What is the membrane permeable to?  Solute: Diffusion or Active Transport Diffusion- moving towards equilibrium Active Transport- moving away from equilibrium  Water: Osmosis  B) Osmosis and Tonicity  Calculate percentages of water (if necessary) Hypertonic- more water inside; water out; cell shrinks Hypotonic- less water inside; water in; cell expands Isotonic- same water on both side; no net movement; cell stays the same size

25. Transport Trash-ketball!  Each group will compete against each other for the chance to shoot for team points.  A question will come on the Powerpoint and all teams will write one answer on a whiteboard.  Teams will put their boards up with the timer goes off.  The team with the best answer will get to shoot.  The best answer will include Any work shown neatly A clear explanation from a person that I choose. So make sure your whole group knows how to get the answer If the person can’t answer I’ll move the next best group POINT VALUES 1 – Slam Dunk 2 – Creative Slam Dunk 3 – Free Thrown 4 – Creative Free Throw 5 – Touching the Rollercoaster There is a 10 second shot clock once I say your answer is correct

26. Trashketball!  A cell of 4% sugar solution is sitting in a solution 9% sugar solution.  1) Draw this solution  2) Is this hypertonic, hypotonic, isotonic?  3) Where does the sugar move?

27. Trashketball!  A cell with a 41% concentration of sugar sitting in a 41% sugar solution.  1) Draw this solution  2) Is this hypertonic, hypotonic, isotonic?  3) Where does the sugar move?

28. Trashketball!  A cell of 25% sugar, 75% water solution is sitting in a solution 15% sugar, 85% water solution.  1) Draw this solution  2) Is this hypertonic, hypotonic, isotonic?  3) If the membrane is permeable to water only, where will the water move?

29. Trashketball  1) What will move- solute or solvent?  2) Which way will it move?

30. Trashketball  1) What will move- solute or solvent?  2) Which way will it move?

31. Trashketball- Tough one!  1) What will move- solute or solvent?  2) Which way will it move? This membrane is NOT permeable to solute

32. Trashketball  If this cell were to undergo active transport…  What moves?  Where?

33. Trashketball  If this cell were to undergo active transport…  What moves?  Where?

34. BRAIN DUMP!  On a piece of paper, write down every word that comes to your mind when you think of passive and active transport. 2 minutes!  After you complete this activity, write a P if it relates to passive, write an A if it relates to active, write B if it relates to both.

35. Review Sheet Work TIME!!  Review sheet!!

36. Exit Question  What are you going to do to prepare for the unit test tonight?
