4
______________ means less crowded.
passive transport
active transport
low concentration
high concentration
5
______________ means crowded.
passive transport
active transport
low concentration
high concentration
6
The primary function of the cell membrane is
to provide support for the cell.
to protect the cell
cell signaling.
to control what moves in and out of the cell.
7
What kind of transport doesn't require the use of energy to move materials across the membrane?
diffusion
all of these don't require the cell to use energy
osmosis
facilitated diffusion
8
Which of these is selectively permeable?
a cell membrane
a window screen
a strainer
all of these are selectively permeable
9
What is concentration?
All of these
the density of a substance
the amount of mass something has
amount of things in a given area
10
__________ is the diffusion of water through a semipermeable membrane.
osmosis
active transport
facilitated diffusion
exocytosis
11
Equilibrium is reached
when movement of particles stops.
at the end of active transport.
only during passive transport.
when particles are evenly distributed through the space.
12
Requires energy; materials enter pockets in cell membrane, then forms vacuole in the cytoplasm?
pinocytosis
endocytosis
phagocytosis
exocytosis
13
The experiment with the food coloring in the water is an example of ______.
diffusion
exocytosis
endocytosis
osmosis
14
Requires energy; vacuole fuses with membrane, contents forced out of cell?
endocytosis
phagocytosis
pinocytosis
exocytosis
15
This type of active transport moves particles out of the cell.
endocytosis
osmosis
exocytosis
diffusion
16
Movement of particles from an area of high concentration to an area of lower concentration is:
diffusion
endocytosis
osmosis
equilibrium
17
Active transport
requires energy
moves materials against a concentration gradient
all of the answers are correct
is usually done by transport proteins in the cell membrane
18

exocytosis
osmosis
endocytosis
diffusion
19

a phospholipid bilayer.
made of proteins.
impermeable.
