hypertonic
isotonic
2
What kind of transport doesn't require the use of energy to move materials across the membrane?
osmosis
diffusion
all of these don't require the cell to use energy
facilitated diffusion
3
The stuff that does the dissolving is the __________.
solvent
solute
solution
suspension
4
"A" is
a protein
a nonpolar fatty acid
a polar phosphate
cholesterol
5
Active transport
all of the answers are correct
is usually done by transport proteins in the cell membrane
moves materials against a concentration gradient
requires energy
6
The primary function of the cell membrane is
to control what moves in and out of the cell.
to protect the cell
to provide support for the cell.
cell signaling.
7
Passive transport
moves particles against a concentration gradient.
requires energy.
doesn't require energy.
moves particles from a high to a low concentration.
8
Water enters, cell swells; lower solute concentration outside the cell than inside = __solution
hydroponic
isotonic
hypotonic
hypertonic
9
What is concentration?
the amount of mass something has
amount of things in a given area
the weight of a substance
the density of a substance
10
Water leaves, cell shrinks; higher solute concentration outside cell than inside = ? solution
hypotonic
hydroponic
isotonic
hypertonic
11
Requires energy; materials enter pockets in cell membrane, then forms vacuole in cytoplasm = ?
exocytosis
phagocytosis
endocytosis
pinocytosis
12
Equilibrium is reached
only during passive transport.
at the end of active transport.
when movement of particles stops.
when particles are evenly distributed through the space.
13
The basic structure of the cell membrane is
a phospholipid bilayer.
impermeable.
a liquid bilayer.
made of proteins.
14
Movement of particles from an area of high concentration to an area of lower concentration is:
endocytosis
osmosis
equilibrium
diffusion
