1. Wake-up 1.How can you tell the difference between an onion cell and a Elodea cell? 1.Why was the Human cheek cell round and not square? -Turn in Wake-up and Animal/Plant Cell Lab from Friday

2. Plasma Membrane and Cell Wall Christopherson

3. Fill in the chart at the top of your notes. Use your notes if necessary.

4. Membrane: Prokaryotic Cell

5. Membrane: Eukaryotic Cell

7. Phospholipid: Structure Phosphate Head Lipid Tail Hydrophilic: LOVES water Hydrophobic: HATES water

8. Phospholipid bilayer Membrane is made up of two layers of phospholipids. With this arrangement in mind, where is the “water” in the diagram? WATER Hydrophilic: LOVES water Hydrophobic: HATES water

9. Location: Surrounds the cell and organelles

10. Function of Phospholipids Controls what comes in and out of cells; the gatekeeper

11. Label Phospholipids on the diagram

12. Cholesterol Location: Found in between the phospholipids in the bilayer. Function: Keeps the membrane together; the phosphate heads are not attached to each other

13. Label Cholesterol on the diagram

14. Proteins Location: Within the phospholipid bilayer

15. 1. Transport Proteins Helps larger substances pass through the bilayer

16. 2. Glycoprotein: Protein with a carbohydrate Helps cells recognize similar cells; similar cells form tissue

17. Label Transport protein and Glycoprotein

18. Carbohydrate Location: On the top of proteins or phospholipids Function: Help recognized similar cells to form tissues OR to recognize foreign substances in the cell

19. * Label Carbohydrate on the diagram

20. Watch me!!! Watch me!!! Shows movement of Bilayer

21. Cell Wall Location: Layer outside of the cell membrane in some organisms Function: Provide structure and support

22. Plants Cell Wall

23. Bacteria Cell Wall

24. Fungus

25. Phytoplankton Cell Wall
