November 2004
UNIT OBJECTIVES: By the end
of this unit, you should be able to

relate this to its function,
2. Explain the concept of selective permeability
using various examples,
3. Compare and contrast the different methods of
cellular transport,
4. Predict the direction of diffusion of a dissolved
substance,

_____ What exactly is cholesterol? What type of
bio-molecule is it? Why is it so important to our health? What
are the major types of cholesterol? Why is too much cholesterol
bad for us? What is the role played by cholesterol in the plasma
membrane? Design a PowerPoint
presentation that includes at least 5 slides that answer these
questions. Include a list of
your sources of
information. 15 pts
_____ Research a specific disorder that is caused by problems
with the plasma membrane of cells. (This will require some
web-quests using search engines or specific websites like
WebMD, CDC.gov, cff.org, etc.) Once you have enough information
to relay to the public,
design an informative pamphlet that can
be distributed in doctors’ offices. Make certain that your
pamphlet includes the cause, symptoms, preventive measures, risk
factors, possible treatments, and
research that is being done on this particular disorder. 15
