IB Biology Year 1, IHS
STEM CELLS and CLONING
Directions: After reading 20.3 from Neil 9e, “Cloning organisms may lead to production of stem cells…” and watching
the 6 stem cell animations online at http://www.stemcellresearch.umich.edu/overview/tutorial.html , answer the
following questions in your journal.
1.
Give an example of a differentiated cell and an undifferentiated cell.
2.
Carrots and frogs were cloned in the 1950’s; “Dolly” the sheep was
cloned in the late 1990’s. After studying
figures 20.17, 20.18 and
20.19, make a labeled generic diagram called “How to Clone.”
3.
What does cloning have to do with stem cells?
4.
Describe the two key features of stem cells.
5.
Compare the capabilities of human embryonic stem cells (hES cells) vs.
human adult stem cells.
6.
From what source do researchers obtain hES cells?
7.
How could scientists prevent the immune system of a patient undergoing
stem cell therapy from rejecting the donated stem cells?
8.
What are iPS cells?
9,
Explain why someone might be opposed to developing medical treatments that use hES cells. Explain why
someone might be in favor of them.
