Answers
1
Why do plants wilt?
plant cells are in a hypertonic solution & the cells shrink
plant cells are in a hypotonic solution & the cells swell
plants don't wilt they get lazy
the plant cells are sleepy
2
What is Structure Y?
Hydrophobic
Hydraulic
Hydrogenous
Hydrophillic
3
What is structure A?
Hydrophillic
Hydraulic
Hydrophobic
Hydrogenous
4
Which cell membrane part helps move large/charged molecules down their concentration gradient?
Carbohydrates
Cholesterol
Sodium potassium pump
Protein channels
5
When is equilibrium reached?
when the molecules are mixed and stop moving
when there is continuous movement, and equal concentrations
when the movement of molecules stops being random
when the rate of change in the solution slows by one half
6
During diffusion, when the concentration of molecules on both side of the membrane are the same
they will move in both directions at an equal rate
they will stop moving
they will move out of the cell
they will move into the cell
7
Why does misting fruits and vegetables with water help them look fresh?
plant cells in a hypotonic solution lose water
vacuoles fill with water due to osmosis
water cannot move through the cell membrane
plants do not have a rigid cell wall
8
At what point in the process of diffusion is equilibrium reached?
equilibrium can never be reached
when there are an equal amount of molecules on each side
when there are more molecules in than out
when there are more molecules out than in
9
If a cell with 60% solute, is placed in a solution with 10% solute, where will water move?
nothing will move
out of the cell causing it to shrink
into the cell causing it to swell
water would enter and leave in equal amounts
10
Why can drinking too much water be harmful?
cells are in a hypotonic solution and will shrink
cells are in a hypotonic solution and will swell
cells are in a hypertonic solution and will shrink
cells are in a hypertonic solution and will swell
11
Solution C is considered
active transport
hypertonic
hypotonic
isotonic
12
The diffusion of water across a selectively permeable membrane is called
pinocytosis
osmosis
active transport
osmotic pressure
13
Solution A is considered
active transport
hypertonic
isotonic
hypotonic
14
What types of materials are expelled from cells during exocytosis?
large molecules like hormones
small molecules such as carbon dioxide
waste
water and glycerol
15
What is a major difference between facilitated diffusion and active transport?
facilitated diffusion moves molecules through the membrane
active transport uses proteins
facilitated diffusion requires energy
active transport moves substances from low to high
16
Which of the following structures serves as the cell's boundary?
chloroplast
channel protein
mitochondria
plasma membrane
17
Which means of particle transport requires no energy?
sodium/potassium pump
endocytosis
osmosis
exocytosis
18
Which term best describes the head of a phospholipid?
Hydraulic
Hydrophobic
Hydrogenous
Hydrophilic
19
A plant cell is placed in a hypotonic solution. What will happen to the plant cell?
it will shrink
it will wilt
it will stay the same
it will enlarge
20
Which term describes the relatively constant internal physical condition of an organism?
homeostasis
organ system
cell specialization
unicellularity
21
What is structure C?
Carbohydrate
Cholesterol
Protein
Phospholipid
22
Which cell membrane structure helps identify the cell?
transmembrane protein
cholesterol
peripheral protein
carbohydrate chain
23
Which of the following is a function of the plasma membrane?
keep the cell wall in place
store water, salt, proteins, and carbs
break down lipids, carbs, and proteins
regulate the movement of material in & out of cell
24
Algae cells are placed in an isotonic solution. Salt is added to the solution, what will happen
they will burst
They will swell
stay the same
shrink
25
What is structure D?
Protein
Cholesterol
Carbohydrate
Phospholipid
26
Which term best describes the tails of a phospholipid?
Hydrophobic
Hydrophilic
Hydraulic
Hydrogenous
27
Explain why more water is moving out the cell than into the cell
more solvent outside the cell than in
more solute in the cell than out
more water inside the cell than out
concentration of water outside the cell is too great
28
An animal cell thats surrounded by fresh water will burst because the hypotonic solution causes
water to move into the cell
solutes to move into the cell
solutes to move out of the cell
water to move out of the cell
29
Which of the following is an example of passive transport?
exocytosis
facilitated diffusion
sodium/potassium pump
endocytosis
30
Which means of particle transport is shown in the figure?
endocytosis
exocytosis
facilitated diffusion
protein pump
31
Solution B is considered
hypertonic
hypotonic
isotonic
active transport
32
What helps keep the cell membrane flexible?
carbohydrate chain
peripheral protein
cholesterol
integral protein
33
Which movement of substances through a cell membrane requires energy?
sodium potassium pump
osmosis
diffusion
facilitated diffusion
34
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
