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/with the
concentration
gradient ([high]
to [low]?
26
Prefix that refers
to a high solute
concentration &
low water
concentration
outside the cell
27
What is
hyper-?
28
Facilitated
diffusion is an
example of this
type of
transport
29
What is
passive?
30
Proteins that
aid
facilitated
diffusion
31
What are
channel
proteins?
32
Direction across
the cell
membrane that
channel proteins
allow movement
33
What is
higher to
lower?
34
This happens to a
channel protein
when it binds with
the molecule it is
transporting
35
What is
change
shape?
36
Type of
molecules that
move by
facilitated
diffusion
37
What are amino
acids or glucose
(large and/or
polar)?
38
Simplest type
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 in both
directions without a
concentration
gradient
45
What is
equilibrium?
46
Type of solution
plants prefer to
be in so that
their cells are
rigid and strong
47
What is
hypotonic?
48
Required by
cells to move
materials by
active
transport
49
What is
energy?
50
Direction of
movement across
a membrane
during active
transport
51
What is low to
high
concentration?
52
Act as cell
membrane
“pumps”
53
What are
channel proteins?
54
Membrane
pumping system
found in animal
cells
55
What is the
sodiumpotassium
pump?
56
57
Process where
cells “drink”
liquid; a type of
endocytosis
58
What is
pinocytosis?
59
Condition
inside the cell
if the outside
of the cell is
hypotonic
60
What is
hypertonic?
61
What happens
to a cell if it is
placed in a
hypotonic
solution
62
What is
expanding/bu
rsting?
63
The type of
solution you are in
if your fingers
and toes begin to
prune
64
What is a
hypertonic
solution?
65
This type of
molecule can
easily diffuse
across the cell
membrane
66
What is small
and/or
nonpolar?
67
What happens
when plant cells
lose osmotic
pressure
68
What is
they wilt?
69
