Cells Alive!
The Web Quest
You and a partner are about to embark on a journey through cyber space to
take a closer look into the world of cells. Follow the instructions very carefully and
answer the questions thoroughly. Good luck and have fun!
Step #1 (10 points)
 Go To: http://www.cellsalive.com/toc_cellbio.htm
 Click on How Big Is A…
 Click Start the Animation
 Click forward through the animation and fill out the following table:
Item Viewing
Human Hair
Magnification
Dust Mite
Ragweed Pollen
Lymphocyte
Red Blood Cells
Baker’s Yeast
E. Coli
Staphylococcus
Ebola Virus
Rhinovirus
Question #1: Where you surprised at how small some of the items were? Why or
why not? Remember to use complete sentences.

Step #2 (10 Points)
 Go back to: http://www.cellsalive.com/toc_cellbio.htm
 Click on Cell Models
 Click on Take Me to the Animation
 Click the Animal Cell
 Click on the following organelles and fill in the blank with the correct
answer:
1. Nucleus - It is enclosed in a double membrane and
_____________________________with the surrounding cytosol via numerous nuclear
pores.
2. Cytosol - __________________________ is the collective term used for the cytosol
plus the organelles suspended within the cytosol.
3. Centriole - Each centriole is a ring of nine groups of groups of fused
___________________________________.
4. Golgi – It is actually a stack of membrane-bound vesicles that are
important in ______________________________macromolecules for transport
elsewhere in the cell.
5. Cell Membrane – Every cell is enclosed in a membrane, a double layer of
____________________________________.
6. Mitochondrion – In short they are the _____________________ centers of the
cell.
7. Vacuole – A vacuole is a membrane-bound sac that plays roles in
intracellular _____________________________.
8. Smooth ER – The ER is a continuation of the outer ______________________
membrane.
9. Ribosomes – They are the site of ________________________ synthesis.
10. Cytoskeleton – As its name implies, the cytoskeleton helps to maintain
cell _______________________________.
