all of these are selectively permeable
a cell membrane
6

diffusion
endocytosis
equilibrium
osmosis
7

cholesterol
a glucose molecule
a protein
a phospholipid
13
The stuff that is dissolved is the _________.
solution
solute
suspension
solvent
14
A cell is in a ____solution when: size doesn't change; water goes in and out at the same rate
hypertonic
isotonic
hydroponic
hypotonic
15
Another name for the cell membrane is
the plasma membrane
the nuclear membrane
the cell wall
the endocytic barrier
16
Water leaves, cell shrinks; higher solute concentration outside cell than inside = ? solution
hydroponic
hypertonic
isotonic
hypotonic
17
The primary function of the cell membrane is
to protect the cell
to control what moves in and out of the cell.
to provide support for the cell.
cell signaling.
18
What kind of transport doesn't require the use of energy to move materials across the membrane?
osmosis
facilitated diffusion
diffusion
all of these don't require the cell to use energy
19
The basic structure of the cell membrane is
a phospholipid bilayer.
impermeable.
made of proteins.
a liquid bilayer.
20
Active transport
requires energy
all of the answers are correct
moves materials against a concentration gradient
is usually done by transport proteins in the cell membrane
21
Passive transport
moves particles from a high to a low concentration.
requires energy.
doesn't require energy.
moves particles against a concentration gradient.
22
What is concentration?
the amount of mass something has
the weight of a substance
the density of a substance
amount of things in a given area
23
__________ is the diffusion of water through a semipermeable membrane.
facilitated diffusion
active transport
osmosis
exocytosis
24
Equilibrium is reached
at the end of active transport.
only during passive transport.
when movement of particles stops.
when particles are evenly distributed through the space.
