MicroViewer Lab: Cell Structure
Introduction: In this activity we will study the principle parts of the cell. The
cell is the basic unit of life. The slides you will examine will help you in
identifying the parts of cells. You will also examine a variety of cells and their
structures. Each major type of cell has variations in structure which aids in
their special functions.
Directions: Read and follow all directions. Examine each slide and study the
description in the folder. After studying each slide and the text, answer the
questions for that section. Draw when you are told to do so. If you don’t know
an answer, go on to the next slide. You may find the answer as you learn more
about the subject.
Slide # 1  Cork
1.
2.
3.
4.
5.
Draw a cork cell.
How would you describe the shape of the cells?
Are the cells joined together?
Why are these cells empty?
The structure you see in the slide is called the ______________. (nucleus,
cytoplasm, cell membrane, or cell wall)
Slide # 2  Onion Skin
1. Why is the skin of an onion an excellent object to study?
2. How many nuclei does each cell have?
3. Most cells have three parts. Name them: ______________,
_______________, and _____________.
Slide # 3  Green Leaf
1. Draw the bundle of cells that make up a vein.
2. What special function can the cells of green plants perform?
3. What is the function of the opening at (E)?
Slide # 4  Cheek Cells
1. Draw one of the cheek cells.
2. Where do these cells come from?
3. Compare this slide with slide # 3. You can find two cell structures in
green leaf cells that are not in human cells. They are: _______________
and ______________.
Slide # 5  Blood Cells
1. This slide shows three kinds of blood cells. Name them: ___________,
___________, and ___________.
2. Which type of cell is most numerous?
3. Can red blood cells reproduce? EXPLAIN!
Slide # 6  Nerve Cells
1. Why can’t we see an entire brain cell in this slide?
2. Why was this slide stained with a dark stain?
3. Can you see the nuclei within these nerve cells?
Slide # 7  Bacteria
1. Draw one of the bacteria shown on the slide.
2. Do the bacteria have a “true” nucleus?
3. What is the name of the group (Kingdom) that bacteria are placed in?
Slide # 8  Virus
1. What kind of microscope is used to see a virus? WHY?
2. Are viruses considered cells? EXPLAIN!
Conclusion Questions:
1. What did you learn from this lab?
2. Which of the cells you looked at are prokaryotic? Which are eukaryotic?
