1
When two solutions with different solute concentration are placed on either side of a membrane, what will happen?
Water will not move
Water will diffuse to the side with less water
Water will diffuse in both directions equally
Water will diffuse to the side with more water
2
Solution B is considered
isotonic
active transport
hypertonic
hypotonic
3
Which means of particle transport is shown in the figure?
protein pump
exocytosis
endocytosis
facilitated diffusion
4
Why will a blood cell burst in a hypotonic solution, but a plant cell won't?
Animal cells have a cell wall
Plant cells don't have a cell membrane
Animal cells have a cell membrane
Plant cells have a cell wall
5
Which movement of substances through a cell membrane requires energy?
active transport
facilitated diffusion
osmosis
diffusion
6
Which of the following structures serves as the cell's boundary?
plasma membrane
mitochondria
chloroplast
channel protein
7
If a cell with 60% solute, is placed in a solution with 10% solute, where will water move?
into the cell causing it to swell
water would enter and leave in equal amounts
out of the cell causing it to shrink
nothing will move
8
An animal cell that is surrounded by fresh water will burst because the osmotic pressure causes
solutes to move into the cell
solutes to move out of the cell
water to move into the cell
water to move out of the cell
9
Why is misting fruits and vegetables with water help them look fresh?
plant cells in a hypotonic solution lose water
plants do not have a rigid cell wall
water cannot move through the cell membrane
vacuoles fill with water due to osmosis
10
Why do plants wilt?
the plant cells are sleepy
plant cells are in a hypotonic solution & the cells swell
plants don't wilt they get lazy
plant cells are in a hypertonic solution & the cells shrink
11
At what point in the process of diffusion is equilibrium reached?
when there are an equal amount of molecules
equilibrium can never be reached
when there are more molecules out than in
when there are more molecules in than out
12
Celery stalks placed in fresh water will become stiff and hard. Celery stalks have
the same concentration of solute than fresh water
a lower concentration of solute than fresh water
a higher concentration of water than fresh water
have a higher concentration of solute than fresh water
13
You are adrift in the Pacific Ocean, and, being thirsty, drink the surrounding seawater. As a result,
You quench your thirst
You dehydrate
Your cells stiffen
Your cells burst
14
Solution A is considered
active transport
isotonic
hypotonic
hypertonic
15
Why is drinking too much water be harmful to athletes?
cells are in a hypotonic solution and will swell
cells are in a hypertonic solution and will swell
cells are in a hypotonic solution and will shrink
cells are in a hypertonic solution and will shrink
16
Which term best describes the tails of a phospholipid?
contains two fatty acids and repels water
contains a phosphate group and attracts water
contains two fatty acids and attracts water
contains a phosphate group and repels water
17
Explain why more water is moving out the cell than into the cell
more water inside the cell than out
more solvent outside the cell than in
concentration of water outside the cell is too great
more solute in the cell than out
18
What types of materials are expelled from cells during exocytosis?
charged ions
small molecules such as carbon dioxide
water and glycerol
large molecules like hormones
19
Algae cells are placed in an isotonic solution. Salt is added to the solution, what will happen
They will swell
shrink
stay the same
they will burst
20
Which term best describes the head of a phospholipid?
contains a phosphate group and repels water
contains two fatty acids and attracts water
contains two fatty acids and repels water
contains a phosphate group and attracts water
21
What is a major difference between facilitated diffusion and active transport?
active transport moves substances from low to high
active transport uses proteins
facilitated diffusion requires energy
facilitated diffusion moves molecules through the membrane
22
Which means of particle transport requires no energy?
endocytosis
exocytosis
sodium/potassium pump
osmosis
23
Which of the following is an example of passive transport?
exocytosis
sodium/potassium pump
facilitated diffusion
endocytosis
24
What helps keep the cell membrane flexible?
peripheral protein
cholesterol
carbohydrate chain
integral protein
25
During diffusion, when the concentration of molecules on both side of the membrane are the same
they will move out of the cell
they will move into the cell
they will continue to move in both directions
they will stop moving
26
Which of the following is a function of the plasma membrane?
break down lipids, carbs, and proteins
store water, salt, proteins, and carbs
regulate the movement of material in & out of cell
keep the cell wall in place
27
Which cell membrane protein crosses both layers of the phospholipid bilayer?
cholesterol
glycocalyx
peripheral protein
transmembrane protein
28
What is osmosis?
diffusion of glucose across the cell membrane
sleeping on a textbook and acquiring knowledge
diffusion of water across the cell membrane
there is no such thing as osmosis
29
Which cell membrane structure helps identify the cell?
peripheral protein
carbohydrate chain
transmembrane protein
cholesterol
30
Red blood cells are isotonic when placed in 0.9% salt water. What type of salt water will cause them to shrivel?
0.1% salt water
0.9% salt water
0% salt water
2% salt water
31
Solution C is considered
isotonic
active transport
hypertonic
hypotonic
32
Which term describes the relatively constant internal physical condition of an organism?
cell specialization
unicellularity
homeostasis
organ system
33
A plant cell is placed in a hypotonic solution. What will happen to the plant cell?
it will stay the same
it will enlarge
it will wilt
it will shrink
34
When is dynamic equilibrium reached?
when there is continuous movement, but no change
when the molecules are mixed and stop moving
when the rate of change in the solution slows by one half
when the movement of molecules stops being random
35
The diffusion of water across a selectively permeable membrane is called
pinocytosis
active transport
osmosis
osmotic pressure
