C
D
They both contain ribosomes.
They both contain mitochondria.
They are both bounded by a plasma membrane.

A
B
C
D
cytology
reductionism
cell fractionation
electron microscopy
_____ 3 Which of the following structures can be found in prokaryotic cells?
A
B
C
D
cytosol
ribosomes
plasma membrane
all of the above
_____ 4 What is the function of a bacterium's pili?
A
B
C
D
adhesion
propulsion
protection
DNA storage
_____ 5 Which of these functions is associated with the eukaryotic cytoskeleton?
A
B
C
D
the beating of cilia or flagella
determining the shape of animal cells
maintaining the position of the nucleus in the cell
all of the above
_____ 6 As a cell increases in size, its volume grows proportionately more than its surface area. Which of the following
statements about the ratio of cell surface area to cell volume is TRUE?
A Cells with more convoluted surfaces have larger surface-to-volume ratios than cells with smooth
surfaces.
B Cells involved in uptake of materials with their environment have large surface areas without greatly
increasing their volume.
C Because of limitations in the surface-to-volume ratio, larger organisms generally do not have
larger-volume cells when compared to smaller organisms.
D All of the above are TRUE statements.
_____ 7 What is the term used to describe the netlike array of protein filaments that maintains the shape of the
nucleus?
A nucleolus
B chromatin
C nuclear lamina
D nuclear envelope
_____ 8 Which of the following INCORRECTLY matches an organelle with its function?
A
B
C
D
lysosome : movement
ribosome : manufactures proteins
mitochondrion : cellular respiration
nucleus : contains most of the genes
_____ 9 Cells can incorporate radioactively labeled amino acids into their proteins. This "tagging" of newly synthesized
proteins enables a researcher to track the location of these proteins in a cell. Imagine an enzyme that will
eventually be secreted by cells in the small intestine. Which of the following is the most likely pathway for
the movement of this protein in the cell?
A nucleus -> ER -> Golgi
B Golgi apparatus -> ER -> lysosome
C ER -> lysosomes -> vesicles that fuse with plasma membrane
D ER -> Golgi apparatus -> vesicles that fuse with plasma membrane
_____ 10 Which of the following is usually formed by phagocytosis?
A
B
C
D
lysosome
food vacuole
central vacuole
contractile vacuole
_____ 11 The central vacuoles of plant cells act as disposal sites for metabolic by-products. They can also perform all
of the following functions EXCEPT
A containing pigments that color the cells.
B storing inorganic ions, such as K+ and Cl-.
C producing ATP through photosynthetic reactions.
D protecting the plant against predators by containing compounds that are poisonous or unpalatable.
_____ 12 Which statement describes a process that is NOT part of the function of the endomembrane system?
A
B
C
D
The Golgi apparatus functions in the modification and sorting of lipids and proteins.
Most of the phospholipids of the endomembrane system are synthesized in the endoplasmic reticulum.
Proteins that will be secreted from the cell are likely to be found in closed spaces bounded by
membranes of the endomembrane system.
Direct physical contact among all the organelles of the endomembrane system is needed to permit
movement of lipid and protein components among the organelles.
_____ 13 Which of the following organelles is NOT bound by a membrane?
A
B
C
D
ribosome
amyloplast
peroxisome
chromoplast
_____ 14 The endomembrane system includes
A
B
C
D
the nucleus, ribosomes, nucleolus, chromatin, and chromosomes.
mitochondria, chloroplasts, peroxisomes, amyloplasts, and chromoplasts.
microtubules, microfilaments, intermediate filaments, centrioles, flagella and cilia.
the nuclear envelope, endoplasmic reticulum, Golgi apparatus, lysosomes, various kinds of vacuoles,
and the plasma membrane.
_____ 15 Chloroplasts are found in
A
B
C
D
all cells.
plant cells.
animal cells.
animal cells and bacterial cells, but not in plant cells.
_____ 16 The observations that chloroplasts and mitochondria each contain their own DNA and that they synthesize
some of their own proteins using prokaryotic-like ribosomes suggests that chloroplasts and mitochondria
A may be of prokaryotic origin.
B contain two or more membranes.
C are part of the endomembrane system.
D are produced by the nucleus of the cell.
_____ 17 Which of the following cellular processes or characteristics is NOT related to the cytoskeleton?
A
B
C
D
contraction of muscle cells
movement of cilia or flagella
production of important organic compounds
movement of the chromosomes during cell division
_____ 18 Which of the following components of the cytoskeleton is involved in the maintenance of cell shape?
A
B
C
D
intermediate filaments
microtubules (tubulin polymers)
microfilaments (actin filaments)
All of the above are involved in the maintenance of cell shape.
_____ 19 Which statement about plant cell walls and the extracellular matrix of animal cells is CORRECT?
A
B
C
D
These structures play no role in determining cell shape.
Sugars and nucleic acids are common components of these structures.
These structures provide for cytoplasmic connections between adjacent cells.
None of the above
_____ 20 The plasma membrane is usually regarded as the boundary of the living cell, but most cells synthesize and
secrete materials of one kind or another that are external to the plasma membrane. These materials are
commonly known as
A intracellular structures.
B intercellular structures.
C supercellular structures.
D extracellular structures.
