Answers

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