Technology
3. A normal cell is anchorage-dependent for growth and mortal.
True
4. A single-celled eukaryotic organism:
A,B,C, above
5. In your own multicellular body, different cells in your body have a division of labor
between them.
True
6. In your own multicellular body, cells with different functions have different DNA.
False
7. Compared to bacteria which of the cell types below are not responsible for
finding food
A, B, C
8. A cell that is anchorage-dependent for growth will also exhibit contact inhibition.
True
9. In Cell Biology what can limit the progress of science?
Technology
10.A cancer cell will be anchorage-dependent for growth and immortal.
False
11.The contractile vacuole of the paramecium is possibly an evolutionary precursor
of the kidney.
True
12.The paramecium discussed in class contained an organelle called the contractile
vacuole. This is the presumed precursor of the:
Kidney
13.Comparing a single-celled eukaryotic organism with a multicellular organism
such as yourself identify the major difference from the list below.
Division of labor
14.A cell that is itself an organism must have a minimum of four needs presented in
lecture. List these four things.
Food, shelter, reproduce, and mating
15.Write a few sentences that explain what limits an individual cell from becoming
more complex.
There are a few things that limit an individual cell from becoming more
complex and that would include having a limited number of
biomolecular machines which affects the division of labor.
16.What limits the paramecium from acquiring more complex functions?
Since it is a single celled organism there is only so much space in the
cytoplasm and therefore the number of biomolecular machines that it
can contain limits it from acquiring more complex functions.

True
7. What limits how big a cell can be?
The surface area to volume ratio
8. The presumed first step in the transition of the primitive, proto-prokaryotic cell
into the primitive, proto-eukaryotic cell was the loss of the cell wall.
