Answers

1
Why is water moving out the cell instead of into the cell?
There is more water inside the cell than out
The concentration of water outside the cell is greater
There is more solvent outside the cell than in
There is more solute in the cell than out
2
At what point in the process of diffusion is equilibrium reached?
equilibrium can never be reached
when there are more molecules in the cell than out
when there are more molecules out of the cell than in
when there are an equal amount of molecules
3
Which of the following structures serves as the cell's boundary?
plasma membrane
channel protein
mitochondria
chloroplast
4
Which term best describes the head of a phospholipid?
contains two fatty acids and repels water
contains a phosphate group and attracts water
contains a phosphate group and repels water
contains two fatty acids and attracts water
5
When is dynamic equilibrium reached?
when the rate of change in the solution slows by one half
when there is continuous movement, but no change
when the movement of molecules stops being random
when the molecules are mixed and stop moving
6
The diffusion of water across a selectively permeable membrane is called
pinocytosis
osmosis
osmotic pressure
active transport
7
Solution B is considered
isotonic
hypertonic
hypotonic
active transport
8
What helps keep the cell membrane flexible?
cholesterol
peripheral protein
carbohydrate chain
integral protein
9
Why do misting fruits and vegetables with water help them look fresh?
plants do not have a rigid cell wall
plant cells in a hypotonic solution lose water
water cannot move through the cell membrane
vacuoles fill with water due to osmosis
10
Solution C is considered
hypertonic
hypotonic
isotonic
active transport
11
What type of materials are expelled from cells during exocytosis?
large molecules like hormones
charged ions
small molecules such as carbon dioxide
water and glycerol
12
Algae cells are placed in an isotonic solution. Salt is added to the solution, what will happen
shrink
they will burst
They will swell
stay the same
13
A plant cell is placed in a hypotonic solution. What will happen to the plant cell?
it will enlarge
it will stay the same
it will shrink
it will wilt
14
Which term describes the relatively constant internal physical condition of an organism?
homeostasis
cell specialization
organ system
unicellularity
15
Which type of particle transport is shown in the figure?
endocytosis
protein pump
facilitated diffusion
exocytosis
16
Which of the following is a function of the plasma membrane?
store water, salt, proteins, and carbs
keep the cell wall in place
regulate the movement of material in & out of cell
break down lipids, carbs, and proteins
17
Which type of particle transport does not require energy?
osmosis
sodium/potassium pump
endocytosis
exocytosis
18
Solution A is considered
isotonic
hypotonic
active transport
hypertonic
19
Which of the following is an example of passive transport?
facilitated diffusion
exocytosis
sodium/potassium pumps
endocytosis
20
Which movement of substances through a cell membrane requires energy?
facilitated diffusion
osmosis
active transport
diffusion
21
What is osmosis?
sleeping on a textbook and acquiring knowledge
diffusion of glucose across the cell membrane
there is no such thing as osmosis
diffusion of water across the cell membrane
22
Why is drinking too much water be harmful to athletes?
cells are in a hypotonic solution and will shrink
cells are in a hypertonic solution and will shrink
cells are in a hypotonic solution and will swell
cells are in a hypertonic solution and will swell
23
Which term best describes the tails of a phospholipid?
contains a phosphate group and repels water
contains a phosphate group and attracts water
contains two fatty acids and attracts water
contains two fatty acids and repels water
24
An animal cell that is surrounded by fresh water will burst because the osmotic pressure causes
solutes to move into the cell
water to move out of the cell
water to move into the cell
solutes to move out of the cell
25
If a cell with 60% solute, is placed in a solution with 10% solute, where will water move?
out of the cell causing it to shrink
into the cell causing it to swell
water would enter and leave in equal amounts
nothing will move
26
During diffusion, when the concentration of molecules on both side of the membrane are the same
they will continue to move in both directions
they will move into the cell
they will move out of the cell
they will stop moving
27
What is a major difference between facilitated diffusion and active transport?
facilitated diffusion moves molecules through the membrane
facilitated diffusion requires energy
active transport moves substances from low to high concentration
active transport uses proteins
