  2. “Cells Alive” Web Quest

  3. Purpose: In this activity, you will discover different kinds of cells. You will learn about specific cell structures and their function.

  4. Procedure:

  5. To begin go to www.cellsalive.com

  6. Select “Cell Biology” from the left hand menu

  7. Visit the “How Big is a…?” section of the site to get a better perspective on the variations of cell size. You should see an image of a person holding a pinhead.

  8. Part A. HOW BIG IS A...."

  9. Here you will look at objects found on the head of a pin. Your job is to rank them in order of size on the chart below and estimate the length of each (in nanometers, micrometers, or millimeters). The line in the bottom right corner of the screen is used to help you estimate. You do not need to record this information on this sheet.

  10. Part B. LABEL DIAGRAMS

  11. Next, under Cell Biology, click on Cell Models and select “Bacterial Cell”. In this section you will discover the significance of the bacterial cell and its parts!

  12. Explain the function of the labeled parts # 1-6:

  13. 1.

  14. 2.

  15. 3.

  16. 4.

  17. 5.

  18. 6.

  19. Part C: ANIMAL CELL MODEL • For this model, you will need to click on the various parts of the cell to go to a screen that tells you about the parts. Answers to the following questions are found there

  20. What is the nucleus seen in both the animal and plant cell made of, what is so important about it?

  21. What is the specific function of the nucleolus?

  22. What are ribosomes involved with?

  23. What is the cell wall made of and what is its function?

  24. What makes the plant cells green?

  25. What is the function of chloroplasts? • Name: _________________ Galoob /Biology date: ______________ Period: __

  35. Next, under Cell Biology, click on Cell Models and select “Bacterial Cell”. In this section you will discover the significance of the bacterial cell and its parts!

  36. Explain the function of the labeled parts # 1-6:

  37. 1. plasma membrane: regulates transport of materials into or out of cell

  38. 2. capsule: protects the bacterial cell

  39. 3. cell wall: maintains the shape of the bacteria
