Unit 5: Into the Cell(s) (BIOL101)Questions and answers
Eukaryotic cells move their organelles using
cilia.
flagella.
the plasma membrane.
the endomembrane system.
the cytoskeleton. - correct answer-the cytoskeleton.
Chloroplasts and mitochondria are similar in that they both
are involved in helping to maintain cell shape.
contain DNA.
are membranous sacs involved in storage.
are involved in cellular waste processing.
are involved in protein production for the cell. - correct answer-contain DNA.
Compared with a eukaryotic cell, a prokaryotic cell
does not require energy.
is larger.
has no method of movement.
is not living.
lacks organelles beyond ribosomes. - correct answer-lacks organelles beyond ribosomes.
The stack of thylakoids labeled "A" in this figure is called
cristae.
stroma.
thylakoid space.
chloroplast.
granum. - correct answer-granum.
Which feature is found in all cells?
cell wall composed of cellulose
nucleus containing DNA
plasma membrane composed of phospholipids
nucleoid region that contains DNA
flagella - correct answer-plasma membrane composed of phospholipids
What does the folding of the mitochondrial inner membrane, shown here, provide?
increased surface area for photosynthesis
greater ability to remove waste from the cell cytosol
,greater ability to allow for osmosis
increased space for protein synthesis
greater surface area for ATP production - correct answer-greater surface area for ATP
production
A cell being observed under a microscope has a cell wall, plasma membrane, ribosomes,
and chromosomal material that is not found in a nucleus. Based on this information, the cell
could be a
bacterial cell.
cell from a fish.
cell from a cactus.
cell from a mushroom.
cell from a paramecium. - correct answer-bacterial cell.
Carrie would like to observe the cilia on the surface of a live paramecium—a single-celled
organism. The best device to do this would be a
light microscope.
magnifying glass.
unaided eye.
dissecting microscope.
electron microscope. - correct answer-light microscope.
The main structural component of a plant cell wall is
middle lamella.
cytoskeleton.
cellulose.
plasmodesmata.
extracellular matrix. - correct answer-cellulose.
What must materials pass through to enter or leave a cell?
lysosome
vacuole
ribosome
plasma membrane
nucleus - correct answer-plasma membrane
Which of the following is an incorrect match?
mitochondria - production of cellular ATP
smooth endoplasmic reticulum - storage of water
ribosomes - protein synthesis
Golgi apparatus - protein alteration and packaging
lysosomes - cellular digestion - correct answer-smooth endoplasmic reticulum - storage of
water
Which of the following is an incorrect match of molecule to the location where it is principally
used?
DNA - nucleus
rRNA - cytoplasm
, glucose - lysosome
mRNA - nucleus and cytoplasm
proteins - ribosome - correct answer-glucose - lysosome
Which of the following statements describes the function of a chloroplast?
It stores water.
It converts chemical energy into heat energy.
It converts light energy into chemical energy.
It manufactures proteins.
It aids in intracellular digestion. - correct answer-It converts light energy into chemical
energy.
Which of the following organelles would form a membrane-bound package, also known as a
vesicle?
mitochondria
chloroplasts
lysosomes
Golgi apparatus
ribosomes - correct answer-Golgi apparatus
Without receptor proteins, a cell would not be able to
transport water into the cytoplasm.
perform metabolic reactions.
bind to signal proteins from other parts of the body.
allow the passage of H ions into the cell.
divide. - correct answer-bind to signal proteins from other parts of the body.
In bacterial cells and plant cells, cell walls function in
maintaining cell shape.
moving organelles throughout the cell.
modifying lipids and proteins.
producing the cytoskeleton.
containing DNA. - correct answer-maintaining cell shape.
Mitochondria are found in
animal cells only.
plant cells.
neither plant cells nor animal cells.
animal cells and bacterial cells only.
both plant cells and animal cells. - correct answer-both plant cells and animal cells
Which statement below is correct when comparing plant and animal cells?
Both plant and animal cells have a plasma membrane and a cell wall.
Both plant and animal cells have a plasma membrane, and plant cells also have a cell wall.
Plant cells only have a cell wall, and animal cells only have a plasma membrane.
Plant cells only have a plasma membrane, and animal cells only have a cell wall.
