QUESTION 1
What will happen to a cell if it were
placed in an isotonic solution?
A) Get Bigger
B) Get smaller
C) No change in size
Why? Equal water concentrations inside and outside the cell
QUESTION 2
What will happen to a cell if it were placed in a
hypertonic solution?
A) Get Bigger
B) Get smaller
C) No change in size
Why? Water will leave the cell
QUESTION 3
What will happen to a cell if it were
placed in a hypotonic solution?
A) Get Bigger
B) Get smaller

Why? Water will enter the cell
QUESTION 4
Which one requires energy?
A)
B)
C)
D)
diffusion
facilitated diffusion

the cell?
A)
B)
C)
D)
Ribosome
Mitochondria
Golgi Apparatus
Cell Membrane
Question 8
What is the “BASIC UNIT” of life?
A)
B)
C)
D)
Atoms
Cells
Molecules
Compounds
Atoms are smaller than cells but they are NOT alive
Question 9
The diagram to
the right shows
that….
A)
B)
C)
D)
That 2 prokaryotes made 2 eukaryotic cells
That 2 eukaryotic cells made 2 prokaryotic cells
That 2 prokaryotic cells made 1 eukaryotic cell
That 2 prokaryotic cells broke apart to form a eukaryotic
cell
Question 10
When you see the words…..”maintain a
stable internal environment”, you should
think?
A) Active transport
B) Concentration gradient
C) permeability
D) homeostasis (a state of balance)
Question 11
What component of the cell membrane
helps communicate the most with other
cells?
A)The proteins
B)The carbohydrates
C)The lipids
D)They don’t communicate
Question 12
What is the final goal of diffusion?
A)
B)
C)
D)
Cells like to move around stuff
To move as much stuff as possible
To reach a concentration equilibrium
To move from Low to High concentration
Question 13
Facilitated diffusion is a process that
involves the movement of?
A) Water molecules
B) Stuff from Low to High concentrations
C) small molecules through the proteins
D) LARGE molecules though the proteins
Question 14
What is a selectively permeable
membrane?
A) A membrane that NOTHING can get in
B) A membrane that everything can get in
C) A membrane that only some things can
get in
Question 15 (What is at A? The Golgi Apparatus
Question 16 (What is at D? ) The Nucleus
Question 17 (What is at E? ) The Ribosomes
18. The picture below represents a container
separated by a membrane. The black dots
represent glucose molecules. According to the
diagram, in which direction will osmosis occur if
the membrane is impenetrable to the glucose.
This question is asking about the direction of osmosis (water). The side marked A has more pure
water than side B, therefore Osmosis will occur to the right. In this question we are NOT focusing
on the particles, we are looking at WATER concentration.
19. A lab technician needs to determine whether
cells in a test tube are prokaryotic or eukaryotic.
The technician has several dyes she could use to
stain the cells. Four of the dyes are described in
the table below.
Which dye could the technician use to determine
whether the cells are prokaryotic or eukaryotic? Since the
nucleus is a distinctive feature then “Nile Blue” is the dye the technician
should use to determine if it’s prokaryotic or eukaryotic
20. What type of transport is being used to
move the top H+ molecule?
The example
in the box is
Active
Transport.
There is ATP
present and
the molecule
is moving
from LOW to
HIGH
concentratio
n through
the protein.
21. What type of transport is being used to
move the sucrose molecule?
The example
in the box is
Facilitated
Diffusion.
The
molecule is
moving
through a
protein and
NO ATP is
needed.
*Hint…what process do
you know it is NOT
22. What is part D
in the diagram?
What does it do for
the cell?
“D” is the protein component of
the cell membrane. It allows
LARGE molecules to pass in and
out of the cell.
A kidney consists of a large number of very small tubes called kidney tubules. Some of the cells which line these
tubules are able to absorb glucose. The diagram shows how these cells absorb glucose from the contents of
the tubule and secrete it into the blood.

channel
Glucose moves into the cell by facilitated diffusion. Osmosis also takes place across the plasma
membrane. Give two differences between facilitated diffusion and osmosis.
