Answers
1
What is a difference between diffusion and active transport?
diffusion moves molecules through the membrane
active transport uses proteins
diffusion requires energy
active transport moves substances from low to high
2
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
store water, salt, proteins, and carbs
keep the cell wall in place
3
In the Diffusion lab, the contents of the beaker did not change color. This indicates
glucose is present
starch is not present
starch is present
glucose is not present
4
Which movement of substances through a cell membrane requires energy?
osmosis
active transport
facilitated diffusion
diffusion
5
The cell membrane is mostly composed of
carbohydrates and lipids
proteins and lipids
proteins and starches
sugars and proteins
6
The diffusion of water across a selectively permeable membrane is called
active transport
pinocytosis
osmosis
osmotic pressure
7
Which molecule will most easily diffuse through the cell membrane?
water
starch
protein
DNA
8
Iodine will change from amber to blue-black if starch is present.
False
True
9
Why does misting fruits and vegetables with water help them look fresh?
plant cells lose water
cells fill with water due to osmosis
water cannot move through the cell membrane
plants do not have a rigid cell wall
10
Why is drinking too much water harmful to athletes?
cells will swell
cells will dehydrate
cells will move
cells will shrink
11
At what point in the process of diffusion is equilibrium reached?
when amount of molecules in and out are equal
when there are more molecules in than out
when there are more molecules out than in
equilibrium can never be reached
12
Explain why more water is moving out the cell than into the cell
more water inside the cell
more solvent outside the cell
more water outside the cell
more solute in the cell
13
Iodine is an indicator for glucose.
False
True
14
Which of the following structures serves as the cell's boundary?
mitochondria
channel protein
plasma membrane
chloroplast
15
During diffusion, when the concentration of molecules on both sides of the membrane are the same
they will continue to move in both directions
they will move faster
they will move into the cell
they will move out of the cell
16
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
17
Which method of transport requires no energy?
endocytosis
osmosis
exocytosis
active transport
18
An animal cell that is surrounded by fresh water will burst because
solutes to move into the cells
water moves into the cells
solutes to move out of the cells
water moves out of the cells
19
The size of a molecule determines whether it will travel across a cell membrane.
False
True
20
Which term describes the constant internal environment of an organism?
cell specialization
organ system
homeostasis
unicellularity
21
Which of the following is an example of passive transport?
exocytosis
endocytosis
sodium/potassium pump
diffusion
22
If a cell with 60% salt is placed in a solution with 10% salt, where will water move?
water would enter and leave in equal amounts
nothing will move
into the cell causing it to swell
out of the cell causing it to shrink
23
Both diffusion and active transport
require enzymes
use ATP
move molecules
use oxygen
24
Algae cells are placed in salt water. What will happen to the cells?
They will swell
stay the same
they will burst
They will shrink
25
When is dynamic equilibrium reached?
when the movement of molecules stops being random
when the molecules are mixed and stop moving
when the rate of change in the solution slows by one half
when there is continuous movement, but no change
26
What changes did you observe in your cell in the Diffusion Lab?
The liquid in the beaker turned blue-black.
The tube turned blue-black
The tube burst
No changes were visible
