Date_____________________ Hour_____
Directions: Use your textbook pages 12-19 and the virtual lab found at
http://bio.rutgers.edu/~gb101/lab1_cell_structure/section8_frames.html to complete the
following information.
1.
Compare plants and animal cells using the Venn diagram below. You should have three items for
each section.
Plants
Both
Animals
2. List the functions of the organelles in the chart.
ORGANELLE
Nucleus
Mitochondria
Chloroplast
Vacuole
Cell Wall
Cell Membrane
Ribosome(s)
Endoplasmic
Reticulum
Golgi Complex
Lysosome
FUNCTION
3. Go to the website in the direction section. You should be on Part II Cells, Part A Plant Cells, and
looking at the Elodea leaf.
4. Read along then click on examine the leaf.
5. Click on higher magnification.
6. Draw the cells that you see in the space below. Label the two main cell organelles that you see.
Add the appropriate color.
7. You probably noticed that each cell contains several chloroplasts. What is the function of a
chloroplast? ______________________________________________________________
_________________________________________________________________________
8. What part of food-making does the chlorophyll do? _________________________________
________________________________________________________________________
9. The other structure in your drawing should have been the cell wall. What does this organelle
provide for a plant? ________________________________________________________
________________________________________________________________________
10. Why don’t animal cells need a cell wall? _________________________________________
_______________________________________________________________________
11. Be sure to try the streaming cytoplasm before you click on the Continue tab at the bottom of the
screen.
12. Go on to look at the onion preparation.
13. Use the space below to draw a picture of the onion cell that you see. Be sure to label the main
structures that you see.
14. How is the slide of the onion different than the slide of the elodea?______________________
_________________________________________________________________________
15. Why do you think the onion cells are a different color than the elodea?
_________________________________________________________________________
_________________________________________________________________________
16. Click Continue at the bottom of the page.
17. You should now be looking at Part II Cells, Part B Animal Cells.
18. Look at the cheek cells under low and high magnification.
19. Use the space below to draw a cheek cell under high magnification. Label any organelles that you
can see.
20. What are three things that you noticed that were different from either/both the elodea and the
onion. ___________________________________________________________________
_________________________________________________________________________
_________________________________________________________________________
21. One organelle that both plant and animal cells have is the “mighty” mitochondria. What is the
function of this organelle? ___________________________________________________
________________________________________________________________________
22. What is DNA and where is it located in the cell? ___________________________________
_________________________________________________________________________
_________________________________________________________________________
23. Click Continue at the bottom of the page.
24. You should be looking at part C – Euglena.
25. What kind of cell is a Euglena (eukaryote or prokaryote)? _____________________________
How can you tell? ___________________________________________________________
26. Click Continue at the bottom of the page.
27. You should now be looking at part D – Bacteria. A bacterium is a prokaryote cell.
28. What is the difference between the Bacterial cell you are looking at here and the plant and animal
cells (eukaryotes) that you saw earlier in this lab? ___________________________________
_________________________________________________________________________
_________________________________________________________________________
29. Choose one of the types of bacteria and draw it below. Be sure to label any structures that you
can identify in the bacterial cell
30. Using your knowledge of plant and animal cells. Determine whether the following pictures are
from plants or animals.

Homework:
The organelles in a cell are rebelling against the nucleus. They all think that they work
too hard, and they want to take a vacation. Write a dialogue between the nucleus and
the other organelles (use your chart). Help each organelle present a case for why it
needs a rest, and then have the nucleus explain what would happen if even one of them
too time off. You may use the space below for your rough copy. You will need to attach
a copy of this using HWS and it must be a Final Copy Product (blue/black ink or typed).
The final version is due: _________________________________________
