Introduction What is a cell, anyway?
Every living thing is made up of cells. In fact,
the cell is the smallest unit of life! Cells
allow you to perform basic functions like eating,
moving, breathing, and much more. You can only
see them with the aid of a microscope, but even
though theyre small, theyre very complex! Each
part of a cell performs a job and cooperates with
other parts to make the cell work. Thats why
its so important to understand what each of
these parts are and what they do. Lets take a
look!

Task Worksheet, Diagrams, and Building My Own!
In this activity, you will complete a provided
worksheet about cell part functions label
parts of an animal, plant, and prokaryotic
cell build your own cell using play dough,
food, Microsoft Paint or any other approved medium

TaskPage One
1.) The animal cell is a eukaryotic cell. Use
the following link to tour an animal cell.
Explore the following cell parts nucleolus,
nucleus, smooth endoplasmic reticulum, lysosome,
mitochondrion, plasma membrane (or cell
membrane), golgi body (or golgi apparatus),
ribosome, and rough endoplasmic reticulum. Label
these on your diagram and fill in the appropriate
boxes on your worksheet. Remember to label your
diagram as an animal cell and tell whether it is
a eukaryote or prokaryote cell.

2.) The plant cell is a eukaryotic cell. Use
the following link to tour a plant cell. Explore
the following cell parts nucleus, golgi body,
nucleolus, rough endoplasmic reticulum, smooth
endoplasmic reticulum, vacuole, chloroplast, cell
wall, mitochondrion, cell membrane, and
cytoplasm. Label these on your diagram and fill
in the appropriate boxes on your worksheet.
Remember to label your diagram as a plant cell
and tell whether it is a eukaryote or prokaryote
cell. (Hint cell part functions can be found
by scrolling down to the blue words)

3.) Bacteria are one-celled organisms. A
bacterium is an example of a prokaryotic cell.
Use the following link to tour a bacterium.
Explore the following cell parts cilia,
ribosome, DNA, cell membrane, cytoplasm, and
flagella. Label these on your diagram and fill
in the appropriate boxes on your worksheet.
Remember to label your diagram as a bacterium and
tell whether it is a eukaryote or prokaryote
cell.

3.) Now that you have completed your worksheet
and diagrams and understand cell structures and
functions, you can begin building your own cell!
You must build either an animal or plant cell.
You are expected to include nine cell parts that
apply to your cell. Use the websites below for
help on building your cell. Supplies are
available in the backroom.

Evaluation Determining Your Grade
The Webquest is worth 200 points total. (The
same as two test grades.) There are 26 total
structures to label on the three diagrams. Each
correctly named structure is worth two points.
(52 pts.) One point is given for giving each
diagram a correct title. (3 pts.) There are
15 cell parts on the worksheet. Every correct
function of these parts is worth two points. (30
pts.) One point will be given for every part
that is correctly identified as belonging to
animal, plant, and/or prokaryotic cell. (15
pts.) Ten points will be given for writing
your name on the worksheet, diagrams, and
constructed cell. (10 pts.) When
constructing your own, 10 points will be given
for every cell part that correctly resembles its
actual structure and belongs to the cell you
chose. (90 pts.)

Conclusion Sending a Thank you
Its hard to think that something so small could
make such a big difference! Cells truly are the
building blocks of life. Now that you understand
the structures and functions of each cell part I
hope you will think about what has to be done for
us to perform basic tasks! Thank you ribosomes,
thank you nucleolus, thank you rough endoplasmic
reticulum, thank you golgi apparatus
A BIG thank you goes to Mrs. Kelly Walbush for
her excellent webquest from which I modeled my
own. Her Webquest can be found here.

This Webquest was designed for a seventh grade
life sciences class by Sarah L. Wood. Virginia
Standards of Learning Addressed in this Webquest
are as follows. LS. 1 The student will plan and
conduct investigations in which d.) models are
constructed to illustrate phenomena LS. 2 The
student will investigate and understand that all
living things are composed of cells. Key
concepts include a.) cell structure and
organelles (cell membrane, cell wall, cytoplasm,
vacuole, mitochondrion, endoplasmic reticulum,
nucleus, and chloroplast) b.) similarities and
differences between plant and animal
cells Please contact me at littlew00d_at_yahoo.com
for additional information such as worksheets and
diagrams used in this webquest.
