does not require energy.
is not living.
is larger. - ANS-lacks organelles beyond ribosomes.
What must materials pass through to enter or leave a cell?
nucleus
lysosome
plasma membrane
ribosome
vacuole - ANS-plasma membrane
Without receptor proteins, a cell would not be able to
perform metabolic reactions.
divide.
transport water into the cytoplasm.
allow the passage of H ions into the cell.
bind to signal proteins from other parts of the body. - ANS-bind to signal proteins from
other parts of the body.
The main structural component of a plant cell wall is
middle lamella.
extracellular matrix.

Where do the vesicles that are being made for secretion from the cell become modified
and packaged?

All cells have some characteristics in common; both prokaryotic and eukaryotic cells
have
cytoplasm, a plasma membrane, and DNA.
a nucleus and a cell membrane.
cytoplasm, a plasma membrane, and a nucleus.
a cell membrane and cytoplasm.
DNA and a cell membrane. - ANS-cytoplasm, a plasma membrane, and DNA.
Without tight junctions in certain tissues,
nutrients would not be able to be passed from cell to cell.
cells would not be able to communicate with each other.
the tissues would not be able to expand and stretch without damage.
fluids may leak out past the barrier the junction would create.
cells would not be able to migrate during their development. - ANS-fluids may leak out
past the barrier the junction would create.
, 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
cell from a fish.
cell from a cactus.
bacterial cell.
cell from a paramecium.
cell from a mushroom. - ANS-bacterial cell.
Which feature is found in all cells?
nucleus containing DNA
plasma membrane composed of phospholipids
cell wall composed of cellulose
nucleoid region that contains DNA
flagella - ANS-plasma membrane composed of phospholipids
What does the folding of the mitochondrial inner membrane provide?
greater surface area for ATP production
increased surface area for photosynthesis
greater ability to allow for osmosis
increased space for protein synthesis
greater ability to remove waste from the cell cytosol - ANS-greater surface area for ATP
production
Which of the following is an incorrect match of molecule to the location where it is
principally used?

Plant cells have plasmodesmata that
connect the cytoplasm of one cell with that of another.
resemble the cytoskeleton of animal cells.
