As a cell increases in size, its volume grows proportionately more than its
surface area.
Cells with more convoluted surfaces have larger surface-to-volume ratios
than cells with smooth surfaces.
Cells involved in uptake of materials with their environment have large
surface areas without greatly increasing their volume.
Because of limitations in the surface-to-volume ratio, larger organisms
generally do not have larger-volume cells when compared to smaller
organisms.
All of the above are TRUE statements.
lysosome : movement
central vacuole : storage
ribosome : manufactures proteins
mitochondrion : cellular respiration
nucleus : contains most of the genes
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
B
C
D
E
ER -> Golgi -> nucleus
nucleus -> ER -> Golgi
Golgi -> ER -> lysosome
ER -> Golgi -> vesicles that fuse with plasma membrane
ER -> lysosomes -> vesicles that fuse with plasma membrane

Which of the following is usually formed by phagocytosis?
A
B
C

The central vacuoles of plant cells perform all of the following functions EXCEPT
A
B
C
D
E
12
C
D
E
Small vesicles are important to the endomembrane system.
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.
Which of the following organelles is NOT bound by a membrane?
A
B
C
D
E
14
containing pigments that color the cells.
storing inorganic ions, such as K+ and Cl-.
producing ATP through photosynthetic reactions.
acting as disposal sites for metabolic by-products.
protecting the plant against predators by containing compounds that are
poisonous or unpalatable.
Which statement describes a process that is NOT part of the function of the
endomembrane system?
A
B
13
lysosome
food vacuole
central vacuole
contractile vacuole
endoplasmic reticulum
lysosome
ribosome
amyloplast
peroxisome
chromoplast
The endomembrane system includes
A
B
C

E
stroma, thylakoids, grana, cristae, cisternae, and cytosol.
the nucleus, ribosomes, nucleolus, chromatin, and chromosomes.
mitochondria, chloroplasts, peroxisomes, amyloplasts, and chromoplasts.
microtubules, microfilaments, intermediate filaments, centrioles, flagella and
cilia.
