Use this worksheet to research and discover more about the complex Eukaryotic cells of Plants,
Animals, Fungus, and Protists.

Use the following questions and directions to navigate through the pages. Record the information to
the questions as you find it.

Find the links for this lab on our science website (no need to type in web addresses):
From the Rio Norte School website pull down the staff menu to see Mr. Fiero and click on that to get to
this site:
    1. Click ion the link “Cellular Biology” in one of the squares in the middle of the home page.
    2. Scroll down on this “Cellular Biology Unit “ web page to the box with “Web Quests and their
    3. Find the list of links for “Cell Web Quest.”
    4. You can simply click on these links rather than type in the address which are shown below.

To begin, go to the website: Cells Alive

Scroll down to and click on: “Start the Animation.” What you are looking at is the head
of a pin with some microscopic items on it. You can zoom in or out with the arrows at the
bottom of the box. To the right of picture of the nail is a list of items that you can click on
them to see them.

First use the magnification bar to see the various sized things –it is also displayed in
green within the picture. By the way this “-“ is one millimeter!
   1. Which item (from the list) is largest (on top of the nail)?
      What is the size of this largest item? _________ micrometers (1 millionth of a
   2. Click on E. coli (the bacteria that lives in your intestines!) What size is it?
      ________ micrometers (1 millionth of a meter).
   3. Click on rhinovirus (a virus that can cause colds) What size is it?? _________
      nanometers (1 billionth of a meter).
   4. What would you basically say about the size of cells?
Next go back to the Cellular Biology webpage of our class site to find the next
link and click on The Virtual Cell and click on it
Click on the ‘virtual cell tour.’
Please click on each organelle to get information. To go to the next page, you have to
cut the organelle or dissolve it, etc. -just follow the directions on the first page, then a
“next “ arrow ► (blue) will appear on the left for you to click on to move to the next
paragraph (like 2 of 3).
                                                                       Make small drawings in the
                                                                   column below for each organelle.

1.Centrioles are only found in __________________ cells.                       Centrioles
 They function in cell _____________________. They
 have _____ groups of _____ arrangement of the protein
 fibers. Draw a picture of a centriole in the box.

2. Lysosomes are called ______________________ sacks.                         Lysosomes
  They are produced by the ________________ body. They
  consist of a single membrane surrounding powerful
  _______________ enzymes. Those lumpy brown structures
  are digestive _____________. They help protect you by
  __________________ the bacteria that your white blood cells
  engulf. _______________ act as a clean up crew for the cell.
  Zoom in and draw what you see.

3. Chloroplasts are the site of ______________________.                      Chloroplasts
  They consists of a __________ membrane. The stacks of disk
  like structures are called the ______________. The
  membranes connecting them are the _________________
  membranes. Zoom in and draw a picture.

4. Mitochondrion is the _______________________ of the Mitochondrion
 cell. It is the site of _______________________. It has a
 ____________________ membrane. The inner
 membrane is where most _______________ respiration
 occurs. The inner membranes is __________ with a very
 large surface area. These ruffles are called ___________.
 Mitochondria have their own ________ and manufacture
 some of their own _______________. Draw a picture of
 the mitochondrion with its membrane cut.
5.Rough Endoplasmic Reticulum (ER) is a series of              Endoplasmic
 double membranes that ________ back and forth between          Reticulum
 the cell membrane and the _______________. These                 (ER)
 membranes fill the ____________________ but you
 cannot see them because they are very
 ___________________. The rough E.R. has
 __________________________ attached to it. This gives
 it its texture. These ribosomes manufacture
 __________________________ for the cell. The ribosomes
 are the ______________________________ which
 manufacture proteins. Draw the rough ER with a ribosome.

6.Smooth E.R. ____________ ribosomes. It acts as a             Smooth ER
 __________________________ throughout the
 cytoplasm. It runs from the cell membrane to the nuclear
 ________________ and throughout the rest of the cell. It
 also produces ___________________ for the cell. Draw a
 picture of the smooth ER.

7.Cell Membrane performs a number of critical functions for       Cell
 the ________. It regulates all that _____________ and
 leaves the cell; in multicellular organisms it allows
 _________ recognition. Draw and shade the cell

8.Nucleus is called the ______________________ of the           Nucleolus
 cell. It is a large __________ spot in eukaryotic cells. It
 _________________ all cell activity. The nuclear
 membrane has many ____________________. The thick
 ropy strands are the _____________________________.
 The large solid spot is the _____________________. The
 nucleolus is a spot of __________________ chromatin. It
 manufactures __________________________. The
 chromatin is _______________ in its active form. It is a
 __________________________________ of DNA and
 histone proteins. It stores the information needed for the
 manufacture of ____________________. Draw a picture
 of the nucleus and its nucleolus.
9.Golgi Body is responsible for packaging                                               Golgi Body
 _________________________ for the cell. Once the
 proteins are produced by the ______________ E.R., they
 pass into the _______________ like cisternae that are the
 main part of the Golgi body. These proteins are then
 squeezed off into the little _________________ which drift
 off into the cytoplasm. Draw a picture of the Golgi Body as
 it is squeezing off the proteins.

Next go back to the Cellular Biology webpage of our class site to find the next link and click on
Cell Craft: Exploring the Cell Through Gaming and click on it.

Click on “Play Game” below the cell animation and have fun!
Simply follow the directions in the interactive animation-this mainly is done by
click on the cell membrane and dragging to move the cell. It has sound!

Just a few questions to answer as you play the cell game:
What is energy molecule that cells use to do things (like move)?
If you want to you can skip movie (about a meteor) to go to level 2.
Hint: You need to make more ribosomes, so click on the nucleolus in the nucleus to make 5 of them at
a time. Also if you cannot make something (like slicer enzymes ) then zoom out and stretch the cell to
the next resource to eat it. Survive the viral attack!!
If you want to you can skip movie (about a meteor) to go to level 3.
Hint: To quickly recycle all the slicer enzymes just drag your cursor all of them and click on the recycle
Keep going as long as you have time for this and interest.
