The Cell: Review Test
1. Which of the following clues would tell you whether a cell is prokaryotic or
eukaryotic? (Concept 6.1 )
a) the presence or absence of a rigid cell wall
b) whether or not the cell is partitioned by internal membranes
c) the presence or absence of ribosomes
d) whether or not the cell carries out cellular metabolism
e) whether or not the cell contains DNA
2. Which statement(s) correctly describe(s) the relationship between the nucleus and
ribosomes of a eukaryotic cell? (Concept 6.2 ) [Hint]
a) The components of the ribosomes are first assembled in the nucleus.
b) The nucleus contains the instructions for protein synthesis by the
ribosomes.
c) All of the proteins of the cell are synthesized on ribosomes bound on
the nuclear envelope.
d) The first two answers are correct.
e) The first three answers are correct.
3. Which statement describes a process that is not part of the function of the
endomembrane system? (Concept 6.4 ) [Hint]
a) Most of the phospholipids of the endomembrane system are
synthesized in the endoplasmic reticulum.
b) Direct physical contact among all the organelles of the
endomembrane system is needed to permit movement of lipid
and protein components among the organelles.
c) The Golgi apparatus functions in the modification and sorting
of lipids and proteins.
d) Proteins that will be secreted from the cell are likely to be found
in closed spaces bounded by membranes of the endomembrane
system.
e) Small vesicles are important to the endomembrane system.
4. A cell has formed a food vacuole as it ingested a food particle. Which of the
following events is not likely to occur associated with the breakdown of that food
particle? (Concept 6.4 ) [Hint]
a) The membrane of the food vacuole is derived from the plasma
membrane.
b) Enzymes for the breakdown of the food are delivered to the food
vacuole from the cytoplasm.
c) Digestion of the food particle occurs in a vesicle with a membrane
that separates the digestion from the cytoplasm.
d) Proteins for digestion of the food are made by ribosomes in the
rough endoplasmic reticulum.
e) Proteins for digestion of the food particle were initially processed in
the Golgi apparatus.
5. Mitochondria are found in _____. (Concept 6.5 ) [Hint]
a) all cells
b) animal cells only
c) plant cells only
d) both plant and animal cells

6. Which of the following functions is not likely to be associated with the
cytoskeleton in eukaryotic cells? (Concept 6.6 ) [Hint]
a) the beating of cilia or flagella
b) maintaining the position of the nucleus in the cell
c) determining which proteins are synthesized by the cell
d) the contraction of muscle cells in animals
e) determining the shape of animal cells
7. Which statement about extracellular structures (plant cell walls and the
extracellular matrix of animal cells) is incorrect? (Concept 6.7 ) [Hint]
a) Some extracellular structures can play a role in determining cell
shape.
b) Some extracellular structures provide for cytoplasmic connections
between adjacent cells.
c) Extracellular structures are barriers that prevent small molecules
from entering or leaving the cell.
d) Proteins and carbohydrates are common components of extracellular
structures.
e) Information can be transmitted from these extracellular structures to
the cytoplasm.

c)
d)
e)
mitochondrion ... photosynthesis
nucleus ... cellular respiration
ribosome ... manufacture of lipids
