8
Helps an organism
maintain
homeostasis by
controlling what
enters or leaves
the cell
9
What is the
cell
membrane?
10
Causes the
concentration of
molecules to be the
same throughout a
space
11
What is
diffusion?
12
State that exists
whenever molecular
concentration is the
same throughout a
space
13
What is
equilibrium?
14
When the
concentration of
solutes inside &
outside the cells
is equal
15
What is
isotonic?
16
Organelle in
paramecia that
pumps out
excess water
17
What is a
contractile
vacuole?
18
Universal
Solvent
19
What is
water?
20
Property that
makes water
such a good
solvent
21
What is
polarity?
22
Solute
concentration
that causes
water to move
into the cell
23
What is
hypotonic?
24
Direction
water moves
in passive
transport
25
What is down
the
concentration
gradient?
26
Prefix that refers
to a high solute
concentration &
low water
concentration
outside the cell
27
What is
hyper-?
28
Facilitated
diffusion is
another example
of this type of
transport
29
What is
passive?
30
Proteins that
aid
facilitated
diffusion
31
What are
carrier
proteins?
32
Direction across
the cell
membrane that
carrier proteins
allow movement
33
What is
higher to
lower?
34
This happens to a
carrier molecule
when it binds with
the molecule it’s
moving
35
What is
change
shape?
36
Type of
molecules that
move by
facilitated
diffusion

of passive
transport
39
What is
diffusion?
40
Direction
molecules
diffuse across
a cell
membrane
41
What is high
to low
concentration?
42
Water
movement
across a cell
membrane
43
What is
osmosis?
44
Point where
molecules continue
to move without a
concentration
gradient
45
What is
equilibrium?
46
Water
pressure
exerted
against plant
cell walls
47
What is
turgor?
48
Required by
cells to move
materials by
active
transport
49

or energy?
50
Direction of
Movement across a
membrane during
active transport

54
Membrane
pumping system
found in animal
cells
55
What is the
sodiumpotassium
pump?
56
57
Process where
cells “drink”
droplets of liquid
58
What is
pinocytosis?
59
Condition of
the cytosol if
the outside of
the cell is
hypotonic
60
What is
hypertonic?
61
A multicellular
organism’s
response to being
in a hypotonic
solution
62
What is
pumping out
solutes?
63
Direction of
water movement
when the solute
concentration
outside the cell is
lower than inside
64
What is water
moving into
the cell?
65
Molecules
soluble in this
can diffuse
through the cell
membrane
66
