hypertonic
isotonic
hypotonic
hydroponic
9
What is structure "D"?
a glucose molecule
cholesterol
a protein
a phospholipid
10
The primary function of the cell membrane is
to provide support for the cell.
to protect the cell
to control what moves in and out of the cell.
cell signaling.
11
Another name for the cell membrane is
the cell wall
the endocytic barrier
the nuclear membrane
the plasma membrane
12
What kind of solution is the red blood cell on the right in?
hypotonic
isotonic
hypertonic
hydroponic
13
Active transport
is usually done by transport proteins in the cell membrane
requires energy
all of the answers are correct
moves materials against a concentration gradient
14
The stuff that is dissolved is the _________.
solution
suspension
solute
solvent
15
The basic structure of the cell membrane is
made of proteins.
a liquid bilayer.
impermeable.
a phospholipid bilayer.
16
What is concentration?
amount of things in a given area
the weight of a substance
the amount of mass something has
the density of a substance
17
Passive transport
moves particles from a high to a low concentration.
moves particles against a concentration gradient.
requires energy.
doesn't require energy.
18
Water enters, cell swells; lower solute concentration outside the cell than inside = __solution
hypotonic
hypertonic
hydroponic
isotonic
19
A cell is in a ____solution when: size doesn't change; water goes in and out at the same rate
isotonic
hypertonic
hydroponic
hypotonic
20
What kind of transport doesn't require the use of energy to move materials across the membrane?

exocytosis
phagocytosis
pinocytosis
endocytosis
