2. What is the function of the ER?
3. What are two structures plant cells have that animal cells do not?
4. Which cell structure breaks down materials for the cell?
5. What does the nucleus contain?
6. Why is what the nucleus contains so important?
7. Choose one other organelle (part of the cell) that has not been mentioned here. What is its
function?
Station 2 – Cell Structure and Function Continued
8. What is one piece of evidence for viruses being alive? What is one piece of evidence for viruses
not being alive?
9. What part of the cell do motor proteins (the “walking machines” in the movie) move along to
transport goods?
10. Animal or plant? ------------------------
11. Animal or plant? --------------------------------------------------
12. Extra point: what is the name of the cell in problem #11?
13. Are bacteria cells usually larger or smaller than animal and
plant cells?
Station 3 - Microscopy
14. What were the three things to remember when carrying a microscope?
15. Would you use the coarse adjustment knob or the fine adjustment knob to slightly adjust focus?
16. Why do we usually dye cells when we look at them under microscopes?
17. What is one thing that you have looked at under a microscope in this class?
18. Below draw what you see under the microscope. After your group is done lower the stage and
prepare it for the next group.
Station 4 – Diffusion and Osmosis
19. Diffusion is the movement of molecules from ____________ concentration to ___________
concentration.
20. Assume that the membrane of the cell is permeable to particles (meaning they can go through
it). What would happen to the particles in this situation?
21. Now assume that the membrane of the cell is NOT permeable to particles. What would happen
to the water if it can pass through the membrane?
22. If the cell in the above questions were an animal cell what would happen to it?
23. In our dialysis lab did water flow toward or away from our red sugar solution?
24. Does more heat make diffusion happen faster or slower?
Station 5 – Body Systems
25. What body system is responsible for controlling the body and sensing information?
26. What body system coordinates the usage of hormones?
27. What is the integumentary system?
28. What system are your kidneys and bladder part of?
29. You are moving around this room from station to station, reading the papers and answering the
questions. What are at least three different systems that you are using to do this?
30. Do body systems work in isolation (alone)?
31. What are at least two body systems that work to protect you? What do they protect you from?
Station 6 – Body Systems Continued
32. What are the levels of organization in creatures? (“Organism” is the largest)
33. What type of tissue had smooth, skeletal, and cardiac versions?
34. What type of tissue is blood?
35. (True/False) Organs are made of only one type of tissue.
36. What type of tissue was organized in tight groups (like soldiers in a line)?
37. Why is this type of tissue organized this way?
38. Which level of organization is considered the smallest living unit of life?
39. Bonus: (True/False) According to cell theory all cells come from other cells.
