Structure and Function of Cells
Go to http://tinyurl.com/9f23x8x or http://sepuplhs.org/high/sgi/teachers/cell_sim.html to access the on-line activity.
On the second screen of the simulation you will see a column with 12 cell organelles and structures. Roll your
mouse over each cell organelle or structure to read some information about it.
1. Fill in columns 2 and 3 below for the structures and organelles in animal and plant cells that perform each
function listed in the first column. All organelles must be used at least once and many are used more than
once. The last column will be completed when you get to #3.
1. Function
2. Animal cell (eukaryotic)
3. Plant cell (eukaryotic)
Synthesis and
modification of
molecules needed by
cells
Storage of substances
(such as DNA, water)
Transport of materials
within, into, and out of
cells
Support for cells
Convert energy for
cells
Break down (digest)
cell wastes or microbes
Chart above is complete and student may proceed

Teacher Signature:
After you have completed the chart above, your task is to build a typical animal cell and a typical plant cell. To
build each type of cell, drag the appropriate organelles or structures into the white space. The organelles and
structures will click into place within the cell.
If you drag an organelle or structure into the cell you are building and it is not part of that cell type, you will get an
error message stating that this organelle or structure is not part of this type of cell. When your cell is complete, you
will get a message stating that it is complete. Remember which parts are in each type of cell.

2. Click continue and complete the Venn Diagram. In the space below, record the Venn diagram you created in
the simulation comparing a typical animal cell and plant cell. Include a label for each circle (animal cell, plant
cell). DO NOT CLICK “CHECK WORK” UNTIL YOU HAVE WRITTEN YOUR RESPONSES BELOW. If all of
your answers are correct when you click “Check Work,” you will not be able to see them or record them. If
you haven’t already recorded your responses, you will have to start over.
3. Label the fourth column on the chart in question #1 bacterial (prokaryotic) cell. Go to

page 44. Use Table 3.1 Functions of Prokaryotic Structures to complete the fourth column.
4. Read the article at http://tinyurl.com/lkrg3b2 or
http://www.scientificamerican.com/article.cfm?id=how-do-antibiotics-kill-b.
a. List four functions of bacterial cells that antibiotics interfere with.
b. Explain why antibiotics are an effective medication to fight bacterial infections.
