Answers
1
What molecules are imbedded in the bilayer?
proteins
glucose
ribosomes
nucleic acids
2
What kind of transport doesn't require the use of energy to move materials across the membrane?
diffusion
osmosis
facilitated diffusion
all of these don't require the cell to use energy
3
The basic structure of the cell membrane is
a phospholipid bilayer.
made of proteins.
impermeable.
a liquid bilayer.
4
What kind of solution is the red blood cell on the left in?
isotonic
hypertonic
hydroponic
hypotonic
5
Requires energy; vacuole fuses with membrane, contents forced out of cell
endocytosis
phagocytosis
pinocytosis
exocytosis
6
Water enters, cell swells; lower solute concentration outside the cell than inside = __solution
isotonic
hypotonic
hydroponic
hypertonic
7
Equilibrium is reached
only during passive transport.
at the end of active transport.
when particles are evenly distributed through the space.
when movement of particles stops.
8
Requires energy; materials enter pockets in cell membrane, then forms vacuole in cytoplasm
endocytosis
pinocytosis
exocytosis
phagocytosis
9
Which of these is selectively permeable?
a strainer
a window screen
all of these are selectively permeable
a cell membrane
10
Another name for the cell membrane is
the plasma membrane
the nuclear membrane
the endocytic barrier
the cell wall
11
Movement of particles from an area of high concentration to an area of lower concentration is:
endocytosis
diffusion
equilibrium
osmosis
12
What kind of solution is the red blood cell in the middle in?
hypertonic
hypotonic
isotonic
hydroponic
13
Water leaves, cell shrinks; higher solute concentration outside cell than inside
hypertonic
hydroponic
hypotonic
isotonic
14
A cell is in a ____solution when: size doesn't change; water goes in and out at the same rate
hypotonic
hydroponic
isotonic
hypertonic
15
The primary function of the cell membrane is
to provide support for the cell.
cell signaling.
to control what moves in and out of the cell.
to protect the cell
16
What kind of solution is the red blood cell on the right in?
hypertonic
isotonic
hydroponic
hypotonic
17
Passive transport
moves particles from a high to a low concentration.
doesn't require energy.
requires energy.
moves particles against a concentration gradient.
18
Active transport
is usually done by transport proteins in the cell membrane
requires energy
moves materials against a concentration gradient
all of the answers are correct
19
__________ is the diffusion of water through a semipermeable membrane.
facilitated diffusion
active transport
osmosis
exocytosis
