Microscopes and Cells WebQuest:
**Use links on Mrs. Sprague’s website to answer the following questions.
1. Microscope History and Types
-Click on “Microscope History”
a) Who were Hans and Zacharias Janssen and why are they important?
b) Who was Robert Hooke and why is he important?
c)
Who was Anton van Leeuwenhoek and why is he important?
2. Types of Microscopes
Click on “Types of Microscopes” and “Studying Cells Tutorial” to fill out the chart below on the different types of
microscopes used by biologists.
Type of
Microscope
How it works
Magnification range
Type of Image seen
(live/dead, 3D/2D)
Pros
Cons
Compound Light
SEM
(scanning electron
microscope)
TEM
(transmission
electron
microscope)
3. Click on “Virtual Digital Microscope”
Try to correctly match all 10 SEM images at SEM Images. List your score out of 10 that you got
correct. Which image was the most interesting?
4. Use the “Bacteria Cell” link to complete the following:
Prokaryotic (Bacteria) Cell
Structure
Nucleoid
Function
Ribosomes
Capsule
Cell Wall
Plasma Membrane
Pili
Flagella
-Label the following prokaryotic cell, using the structures you just described in the above table:
5. Use the “Cells Alive” Link and the Interactive Cell Diagrams to complete the following:
Animal Cell
STRUCTURE
Nucleus
Nucleolus
Cytosol (cytoplasm)
Centrosome
Centriole
Golgi Apparatus
Lysosome
Peroxisome
Secretory Vesicle
Cell Membrane
Mitochondria
Vacuole
Smooth Endoplasmic Reticulum
Rough Endoplasmic Reticulum
Ribosomes
Cytoskeleton
FUNCTION
-Now change to “Plant Cell” and complete the following table of structures UNIQUE to plant cells:
Unique Plant Cell Structures
STRUCTURE
Vacuole (Large)
FUNCTION
Cell Wall
Chloroplast
a) Why does the plant cell have such a large, central vacuole?
b) What does the plant cell’s vacuole have to do with wilting?
c)
What structure do animal cells have that plant cells DO NOT have?
6. Practice labeling and identifying plant and animal cells by clicking the “Cell Inspector” link. How did you do?
7. Check out the images at the” Magnification Module” - List which sample and at which power of magnification you
thought was the most interesting.
8. For Extra Credit you can continue on with the Stem Cell WebQuest (use the last two links).
