Websites #2, 3, & 4:
D. Use these websites to answer the following questions:
1. What are 3 roles of vacuoles in a plant cell?
>
>
>
2. Are vacuoles larger in plant cells or animal cells? WHY???
3. What is the role of the Golgi apparatus in animal cells?
4. Below, sketch a typical Golgi apparatus.
5. What is the cytoplasm?
6. Why does the rough endoplasmic reticulum appear to be rough?
7. Other than DNA, what else is contained within the nucleus of an animal cell?
8. Why is the mitochondria called the “powerhouse of the cell”?
Websites #5 & 6:
E. Use these websites to answer the following questions:
1. Using the table below, identify the “shape name” for the following two bacteria:
 Staphylococcus aureus: ______________
 Pseudomonas aeruginosa: _______________
“Shape Name”
Coccus
Bacillus
Spirillus
Cell Shape
Spherical
Rod-shaped
Spiral-shaped
2. View the Scanning Electron Microscope images of the centric diatom, the dust mite, the bullet
ant, etc. Play around with the focus, contrast, brightness, and magnification. (It’s just kinda cool.)
