is to control what enters
and leaves a cell.
2. Describe an isotonic solution for the cell
pictured below.
45% NaCl
55% water
45% NaCl
55% water
3. Amino acids, sugars, and ions move across the
cell membrane. Their movement from a region of
high concentration to a region of low
concentration is accomplished by special proteins
in the membrane. Which of the following terms
applies to this type of cell transport? **List 3 key
words you used to decide.**
A. active transport
B. facilitated diffusion
C. osmosis
D. transcription

applies to this type of cell transport? **List 3 key

A. active transport
B. facilitated diffusion
C. osmosis
D. transcription
4. List 3 organelles that eukaryotic and
prokaryotic cells have in common.
Cell membrane, Cytoplasm, Ribosomes
**Reminder for your test: They both have
DNA, but Eukaryotes store the DNA in the
nucleus ***
5. Describe the type of solution that each cell is
resting in below. **Hint: hyper, hypo, iso**
Isotonic
Cell A
Hypotonic
Cell B
Hypertonic
Cell C
6. Describe the
function of part D
in the cell
membrane
pictured.
Transport Protein
7. This component of the cell
membrane is used for cell signaling,
it contains the elements CHO in a
1:2:1 ratio
Carbohydrates
8. This part of the cell membrane is used to
transport large molecules and contains the
elements CHON
Transport Protein
9. This part of the cell membrane is has two
hydrophobic fats and a hydrophilic phosphate
Phospholipid Bilayer
10. A cell placed in this type of solution will
not change shape but stay the same
11. A cell in this type of solution will swell and
get larger
12. A cell in this type of solution will shrink,
get smaller.
13. A cell that is 90% water and 10% solute is
placed in a solution that is 80% water. Draw a
diagram representing which way water will flow
and describe what type of solution the cell was
placed in (Hypo, hyper, iso)
90% water inside the cell is greater than 80%
water solution so water will diffuse out of the
cell into the solution.
Hypertonic: The cell will shrink
14. A cell that is 50% water and 50% solute is
placed in a solution that is 60% water. Draw a
diagram representing which way water will flow
and describe what type of solution the cell was
placed in (Hypo, hyper, iso)
50% water inside the cell is less than 60% water
solution so water will diffuse into the cell.
HypOtonic: The cell will swell
15. This organelle is used to make ATP
(energy)
MITOCHONDRIA
16. This organelle is found in both prokaryotic and
eukaryotic cells and is used for protein synthesis
RIBOSOME
17. Streptococcus bacillus is a bacteria with
free floating DNA, what type of cell is it?
PROKARYOTIC
18. Plants have a cell wall made of cellulose and
DNA in a nucleus, what type of cells are plants
made of?
EUKARYOTIC
19. What type of cell is cell A?
Cell A
Cell B
Contains Ribosomes
Contains Ribosomes
Has a Cell wall
Has a cell membrane
Has Endoplasmic Reticulum
Has no membrane bound organelles
20. What type of cell is Cell B?
PROKARYOTE
20. This is a theory that represents how
eukaryotic cells were formed. (pro+pro=eu)
ENDOSYMBIOTIC THEORY
21. When both sides of the cell membrane contain
the same amount of solute the solution is said to
be at _________________.
A.
B.
C.
D.
Endosybiotum
Equilibrium
Diffusion
Osmosis
22. List 3 similarities between prokaryotic and
eukaryotic cells.
• BOTH HAVE DNA
• BOTH HAVE RIBOSOMES
• BOTH HAVE CELL MEMBRANES
• BOTH HAVE CYTOPLASM
23. The hypothalamus is the temperature-regulating centre of the brain.
Changes in core body temperature cause the hypothalamus to send
nerve impulses to the sweat glands, muscles and blood vessels to raise
or lower the temperature. If the core temperature goes up the body
loses heat to bring it down again. If the core temperature goes down the
body will conserve and even generate heat to bring it up again. This
maintaining of internal balance is called___________.
A.
B.
C.
D.
Homepathy
Homeostasis
Homeokarytoic
Homeotelopathy
24. There are 4 types of molecule transport
list all 4.
• DIFFUSION-small particles, high to low, no energy
• OSMOSIS-water only, high to low, no energy
• FACILITATED DIFFUSION-large particles, protein channels, high to low,
no energy
• ACTIVE TRANSPORT-large particles, protein channels, LOW to high,
energy required, ATP
25. This type of molecular transport
uses a protein to move solutes from
an area of high concentration to an
area of low concentration.
FACILITATED
DIFFUSION
*diffusion with “help” from proteins
26. This type of molecular transport
uses energy to move molecules
against the concentration gradient
ACTIVE
TRANSPORT
