What would your hypothesis be if you found a
cluster of fuzzy black growth in an empty plastic
container in your cabinet?
1. The container gave rise to this growth.
2. There were microscopic portions of this
growth that gave rise to this larger colony.
3. The fuzzy growth is not a growth, but part of
the container.
4. The fuzzy growth generated spontaneously
in the container after you put it in the
cabinet.

A male animal has all its sex organs, but can’t
produce sperm. Your hypothesis is that the cells
of the testes:
1. Have malfunctioning Golgi or ER and do not
produce the hormones required for sperm
production.
2. Have malfunctioning lysosomes and do not
produce the hormones required for sperm
production.
3. Do not have nuclei for phospholipid
production.
4. Lack cytoplasm containing the DNA.

A cell’s membrane is not formed properly—it is
not able to act as a barrier to its environment.
What may cause this problem?
1. The ER is malfunctioning and cannot produce the
proteins for the membrane.
2. The ER is malfunctioning and cannot produce the
phospholipids and cholesterol for the membrane.
3. The mitochondria are malfunctioning and cannot
produce the phospholipids and cholesterol for the
membrane.
4. The chloroplasts are malfunctioning and cannot
produce the energy needed to move molecules
across the membrane.

Why would a cell have a prominent ER and
Golgi apparatus?
1. It is a muscle cell and needs to have an excess
amount of processed lipid.
2. It is a bacterial cell and secretes large amounts of
protein antibodies to attack plant and animal cells.
3. It is a leukocyte (white blood cell) and secretes
large amounts of protein antibodies into the blood
stream.
4. It is a plant cell and undergoes the process of
photosynthesis, producing large amounts of
protein.
