We are going to take a tour of the cell. Download and open
your “Cell World” app.
Use cell world to help answer the questions on this sheet
and fill in the pictures in the boxes to the right to the best of
you artistic ability.
*You can also find information in your book in chapter 3 or
http://www.biologyreference.com/ . Use ch. 3 to help you
draw, label, and color each organelle in the box.
The Virtual Cell Worksheet
1. Eukaryotic Cell: How do eukaryotic cells differ from prokaryotic Eukaryotic cell
cells?
What types of organisms are eukaryotic?
2. Centrioles are only found in ____________________ cells. Centriole
They function in cell
______________________.
Draw a picture of a centriole in the box to the right.
3. Cytoplasm definition and functions:
Define ion:
List two examples of ions found in the cytoplasm:
Look up the word osmoregulation. What does that mean?
Cytoplasm:
Lysosomes
4. Lysosomes description and functions (at least 4):
How are they similar to the vesicles and cell membrane?
What is apoptosis?

are
the
site
______________________________in plant cells. It
of Chloroplasts
consists of a _______________ membrane. The stacks of disk
like
structures are called the ________________. The membranes
connecting them are
the ____________________ membranes.
6. Mitochondrion
is
the
___________________ Mitochondrion
______________of the cell. Why does it have that name?
Why are mitochondria unusual organelles (3 reasons)?
Why do some cells have more mitochondria than others?
Draw a picture of the mitochondrion
7. Rough Endoplasmic Reticulum (ER) description and function:
Endoplasmic
(ROUGH ER

*ADD the
What happens to the proteins that are produced by the ER?
Draw the rough ER with ribosome(s) in box to the right.
8. Smooth E.R. description and function:
Smooth ER
Why is it called “smooth”?
What type of cells have more smooth ER?
Draw a picture of the smooth ER.
9. Cell Membrane: What is the function of the cell membrane?
Cell Membrane (FIG 3.17 of
book p. 82)
What is the cell membrane made of?
What does semi-permeable mean?
Why is the cell membrane critical to cell?
10. Nucleus description and function:
Nucleus with chromosome:
What are chromosomes?
What is the nucleus considered to be?

When will nuclear pores allow protein in or out of the
nucleus?
13. Nucleolus description and function:

proteins.
15. Ribosome description and function:
Ribosome
What are the molecules that ribosomes link together to make
proteins?
Describe the two subunits of ribosomes:
What types of cells contain ribosomes?
Part II: Instructions: Go to Cellsalive.com and select “cell models” from the
menu on the left side of the screen. Select the “animal cell” and use the
interactive model to help you label and define the missing animal cell parts:
Label and briefly describe cell parts: nucleus, nucleolus, ribosome,
cytoplasm/cytosol, vacuole, cell membrane, smooth endoplasmic
reticulum, rough e.r., lysosome, mitochondria, golgi body/apparatus,
cytoskeleton (microfilaments and microtubules):
Add and label a flagellum to the cell below. Locate and label where you would
find: chromatin, nuclear pore, nuclear envelope
Helpful additional site: http://biology.tutorvista.com/animal-and-plant-cells.html
Go to the http://cellsalive.com/cells/cell_model.htm and use the plant cell model
to label and define the parts of a plant cell on the back:
Now go to: http://cellsalive.com/cells/3dcell.htm
Label Prokaryotic Cell Parts and then define below
(some of these are in your notes too):
Pili:
Plasmid:
Flagella:
Cell membrane:
Cell Wall:
Nucleoid Region/One Chromosome:
Ribosomes:
Cytoplasm::
