2. What is the difference between the rough and smooth endoplasmic reticulum?

3. Would an animal cell be able to survive without mitochondria? Why or why not?

4. What could you determine about a specimen if you observed a slide image showing the specimen with a cell wall, but no nucleus or mitochondria?

5. Hypothesize why parts of a plant, such as the leaves, are green, but other parts, such as the roots, are not. Use scientific reasoning to support your hypothesis.

Experiment 2: Create a Cell

Post-Lab Questions

1. What cell structures did you place in the plant cell that you did not place in the animal cell?

2. Is there any difference in the structure of the two cells?

3. What structures do cells have for support in organisms that lack cell walls?

4. How are organelles in a cell like organs in a human body?

5. How does the structure of a cell suggest its function? List three examples

6. In the table below, list the items you used to represent the various organelles in your ANIMAL cell. Provide a brief rationale explaining why you selected each item.
