Pindicates
vocabulary not found in the text but will be covered in class notes.
2.
All of the readings should be read with the goal of being able to
discuss/explain the information contained in them.
Section
8.1 Cellular Transport
Section
8.2 Cell Growth and Reproduction
Section
8.3 Control of the Cell Cycle
3.
Record all the material presented in class notes and commit them to
memory.
4.
Have the following expectation questions answered in your notebook.
Be sure to label the group number with your questions
Group 1 Cellular
Transport
-
Explain how osmosis and diffusion
are alike and how they are different.
-
Compare and contrast active
transport and facilitated diffusion.
-
Cells in the human body
constantly use oxygen during metabolism.
Blood contains oxygen. Why
does oxygen diffuse into the cells from the bloodstream?
Group 2 Cell Growth
and Reproduction
1. In what ways is the size of cells determined by diffusion?
2.
Describe the nuclear activities during
a.
Interphase
d. Anaphase
b.
Prophase
e. Telophase
c.
Metaphase
3.
What is the role of the spindle fibers in mitosis?
4.
Why is it necessary for a cell’s chromosomes to be distributed to its
daughter cells in such a precise manner?
5.
How is cytokinesis different in plants and animal cells?
6. At one time, interphase
was referred to as the resting phase of the cell cycle.
Why do you think this description is no longer used?
Group 3: Control of
the Cell cycle
1.
What role do oncogenes and tumor suppressor genes play in cell division?
2.
What is contact inhibition? What
happens to contact inhibition when cells begin dividing out of control?
3.
Describe how genes control the cell cycle.
4.
What is the difference between a benign and a malignant tumor?
5.
The following labs should be handed in with discussion questions written
out and answered in complete sentences. Conclusion,
if assigned, should include restatement of purpose, summary of data, data
interpretation, and evaluation of hypothesis.

6.
Know how to convert from one unit to another in the metric system using
factor label method.
7.
Know all organelles, their location in the cell and their function.
8.
Be able to recognize the different stages of mitosis in a prepared
microscope slide.
Extra Credit: All
homework must be turned in on time for this chapter in order to be eligible.
Must be turned in before taking the test. (maximum 3 pts on test)
Gather information
on melanoma, a type of skin cancer. Look
for information dealing with the cause, symptoms, and treatment.
Use at least 3 different sources that you report in your written paper.
(Remember: search engines do
not count as a source. They are a way to find a list of sources.
Report the actual page addresses for the information you use)
Also you must use 2 different types of sources i.e. books, encyclopedia,
internet. You may not use 2
internet sites. Your paper must be
typed, 12 pt. Font, black ink, with 1 inch margins on all sides.
