ASU BIO 181 EXAM 1- PRACTICE QUESTIONS
WITH MOST RECENT UPDATED ACTUAL
ANSWERS
The paramecium discussed in class contained an organelle called the contractile vacuole. This is the
presumed precursor of the: - answer ✔✔-kidney
A cell that is anchorage-dependent for growth will also exhibit contact inhibition. - answer ✔✔-true
In your own multicellular body, cells with different functions have different DNA. - answer ✔✔-false,
their DNA is identical but different gene expression
The contractile vacuole of the paramecium is possibly an evolutionary precursor of the kidney. - answer
✔✔-true
The paramecium swims by way of using a flagella. - answer ✔✔-false, they use cilia
In order to examine cells which are smaller than can be detected by the human senses what needs to be
used? - answer ✔✔-tehcnology
Compared to bacteria which of the cell types below are not responsible for finding food - answer ✔✔-
Lymphocyte
Macrophage
Fibroblast
A cancer cell will be anchorage-dependent for growth and immortal. - answer ✔✔-false, a cancer cell is
anchorage-independent for growth and immortal
A normal cell is anchorage-dependent for growth and mortal. - answer ✔✔-true
, A cell that is itself an organism must have a minimum of four needs presented in lecture. List these four
things. - answer ✔✔-a cell needs to find food, shelter, reproduce, and mate. Also be able to escape
predators.
In your own multicellular body, different cells in your body have a division of labor between them -
answer ✔✔-true
What limits the paramecium from acquiring more complex functions? - answer ✔✔-the number of
biomolecular machines it can contain within itself
Write a few sentences that explain what limits an individual cell from becoming more complex. - answer
✔✔-It has a limited number of biomolecular machines that a cell can contain and limits it from being
more complex. It has to do everything for itself. Also has a certain number of parts with which to change
its engineering, thereby changing its function.
In Cell Biology what can limit the progress of science? - answer ✔✔-technology
A single-celled eukaryotic organism: - answer ✔✔-Has a limited number of biomolecular machines.
Must find food, shelter, a mate and reproduce
Escape from predators
Comparing a single-celled eukaryotic organism with a multicellular organism such as yourself identify the
major difference from the list below. - answer ✔✔-Division of labor
We are made up of ....% water - answer ✔✔-50-70%
Explain how the vesicles are carried from the Golgi apparatus to the plasma membrane. - answer ✔✔-
Proteins are synthesized by ribosomes and enter the rER (rough endoplasmic reticulum) . Vesicles bud
off from the rER and carry proteins to the Golgi.
The Golgi modifies proteins, and then the vesicles bud off from the Golgi and carry modified proteins to
the plasma membrane.
The plasma membrane gets new lipids from: - answer ✔✔-None of the above.
