2. First Five In your notebooks silently answer the following: Perform a self evaluation on yourself in regards to the quiz we took. Did you study? How did you study? How well do you think you did? If you think you did poorly why do you think you should do next time? If you think you did well, explain why.

3. Announcements Past Due: Kingdom Classification Lizard Phylogeny Check your grades

4. Presentation Time Presentations should last roughly 2 minutes. You will receive a graded rubric next class. Once presentations are done everyone needs to perform an evaluation on themselves and their group members. This will be part of your rubric. Did everyone contribute? If no, who didn’t If yes, what was the contribution.

5. Key Ideas of Cells  Cells are highly organized  Different parts of the cells have specific functions  Today, we will be focusing on “Eukaryotic” cells, meaning plant and animal cells.

6. Variation in Cells Types of Cells EukaryoticPlantAnimalProkaryoticBacteria Important for now

7. What are organelles? What are organelles?  Definition: Organelles are specialized cell parts that carry out a specific job  You have a body that has organs that do specific things so your whole body will work. An organelle is a little organ for the cell.

8. Nucleus Nucleus “The Control Center”; a large organelle in the center of the cell that controls everything that happens in the cell Stores and protects all genetic material (DNA) needed to make proteins

9. Control center for plant and animal cells: Chromosome = coiled DNA: contains instructions for characteristics of an organism. Chromatin = protein composing chromosomes

10. Let’s use an analogy: The cell is like a nightclub! Nucleus is the DJ The DJ controls what music gets played at the club and also holds all the CDs/ mp3 songs at his booth The Nucleus is like a control center for the cell and stores all the DNA (genetic information) for the entire cell!

11. Cytoplasm Cytoplasm Jelly-like fluid that holds all the organelles outside of the nucleus Provides support for the cell and structures

12. Cell Analogy: The Nightclub Cytoplasm is the air inside the club All dancers in the club need air that contains all the gases to survive and have a good time The cytoplasm in the cell supports all the organelles and has all the needed molecules for the cell to survive

13. Cell membrane Cell membrane Partially permeable barrier that surrounds the cytoplasm Controls what goes into and out of the cell

14. Cell Analogy: The Nightclub The cell membrane is the bouncer at the door of the club The bouncer decides who gets to enter the club and who should be kicked out The cell membrane protects the cell by controlling what enters and leaves the cell

15. Stop-and-jot What is a body part that is similar to each of the cell parts we just discussed? Nucleus Cytoplasm Cell membrane

16. Ribosome Ribosome a tiny organelle that helps the cell make protein by linking amino acids together. It floats freely in the cytoplasm Function: Links amino acids together to form proteins for the cell

17. Cell Analogy: The Nightclub Ribosome is like the snack machine The snack machine in the club is there to feed hungry dancers and is usually small and out of sight from everyone. It takes the code you enter and gives you a snack. Most snacks contain protein to satisfy your hunger. The ribosome is very small and helps make proteins which fuel all the cells’ processes.

18. ENDOPLASMIC RETICULUM (ER):  Network of tubes that produces, processes, distributes proteins  Rough or smooth

19. Endoplasmic Reticulum “ Rough” with Ribosomes for protein synthesis “Smooth” = Membrane “highway” For transport of materials

20. Cell Analogy: The Nightclub The chef/bartender of the club Takes protein materials (food or drink) and modifies it to meet the need of the customer

21. GOLGI APPARATUS: Membrane bound sacs that process, package, sort, and deliver proteins

22. Cell Analogy: Golgi Apparatus Waitress at the club that makes sure to deliver your order to your table

23. Mitochondria Mitochondria a bean-shaped organelle that creates all the energy the cell needs to survive Second-largest organelle

25. Cell Analogy: The Nightclub Mitochondria are like the speakers of the sound system. The speakers play all the music in the club which gives dancers the energy to have a good time. Music is similar to energy! The mitochondria supply all the energy needed for the cell to survive

26. Chloroplast= absorbs light, changes light energy into chemical energy for photosynthesis = GrEEN Sacks

27. VACUOLE: Sac-like structure in the middle of the cell that stores water, food, enzymes that the cell needs

28. Vacuole = storage for food and water Why are plant vacuoles larger than animal vacuoles? Plant Vacuole

29. Do you see 2 Contractile vacuoles in this Paramecium? Some Animal cell vacuoles pump water out by contracting :

30. Cell Analogy Storage basement beneath the club to hold extra equipment, food, drinks, and tables

31. Lysosome: Contains digestive enzymes Breaks down large molecules

32. First Five Silently review today's worksheet and grab a computer

33. Cell Structure Web Activity 1. Get a computer and the handout 2. Complete the first side of the handout using the laptop 3. Use colored pencils to color the pictures on the back 4. Answer the questions

34. Review Time

35. Name that Organelle! Choose the name that matches the organelle being described: Nucleus Cytoplasm Cell membrane Ribosome Mitochondria Endoplasmic reticulum Vacuole Chloroplast

36. Round 1 Jelly-like material that supports the cell and holds all molecules needed by the cell

37. Contains enzymes to digest and breakdown material

38. Links amino acids together to form proteins for the cell

39. Stores water, food, enzymes that the cell needs

40. Thin layer that controls what materials can move in and out of the cell

41. Contains enzymes that process, package, sort, and deliver proteins

42. Stores and protects all genetic material (DNA) needed to make proteins

43. Produces, processes, distributes proteins

44. Creates all the energy the cell needs to survive

45. Bonus: Label this diagram First, on your whiteboard, number from 1 to 10. Then, you will write down the names of the cell parts next to each number.
