BSC 1010C - Chapter 6: A tour of the Cell Questions With
Complete Solutions
__________ are membrane-bound metabolic compartments that
specialize in the production of hydrogen peroxide (H2O2) and
its conversion to water. Correct Answers Peroxisomes
A protein that ultimately functions in the plasma membrane of a
cell is most likely to have been synthesized __________.
Correct Answers In the rough endoplasmic reticulum
A substance moving from outside the cell into the cytoplasm
must pass through __________. Correct Answers The plasma
membrane
Animal cells have unique organelles called __________ that are
composed of structures called __________. Correct Answers
Centrosomes; centrioles
Bacterial cells are prokaryotic. Unlike a typical eukaryotic cell
they __________. Correct Answers Have no membrane-
bounded organelles in their cytoplasm
Basal bodies are most closely associated with which of the
following cell components? Correct Answers Cilia
Cell junctions in plant cells are called __________, and
communicating junctions in animal cells are called __________.
Correct Answers Plasmodesmata; gap junctions
, Cell motility, which includes changes both in cell location and
in the movement of cell parts, requires interactions of the
cytoskeleton __________. Correct Answers With motor
proteins
Cells are small because __________. Correct Answers Of the
geometric relationships between surface and volume
Cilia and flagella move due to the interaction of the cytoskeleton
with what? Correct Answers Motor proteins
Dye injected into a plant cell might be able to enter an adjacent
cell through __________. Correct Answers Plasmodesmata
Evidence that supports the prokaryotic origins of mitochondria
and chloroplasts are all of the following except __________.
A. that the ancestral prokaryote had two outer membranes,
which became the double membranes of the mitochondria and
chloroplasts
B. that mitochondria and chloroplasts have multiple copies of
linear DNA molecules associated with their inner membranes
C. that mitochondria and chloroplasts can grow and reproduce
within a cell Correct Answers B. That mitochondria and
chloroplasts have multiple copies of linear DNA molecules
associated with their inner membranes
In terms of cellular function, what is the most important
difference between prokaryotic and eukaryotic cells? Correct
Answers Eukaryotic cells are compartmentalized, which allows
for specialization
