Question # 1
Think about the Carrot Lab. Draw a quick
picture about how the water moved while the
carrot was in the salt water cup.
Question # 1 Answer
Think about the Carrot Lab. Draw a quick

Answer-
Question # 2- 2 points
What happened when we added a few drops of
food coloring to the cup of water?
How did the dye move through the water?
Question # 2 Answer
What happened when we added a few drops of
food coloring to the cup of water?
ANSWER- Concentrated at the top of the glass.
How did the dye move through the water?
ANSWER- Moved downward until it DIFFUSED
evenly throughout the glass
Question # 3
When put in certain solutions, an animal cell
could burst. What type of solution would
cause this?
Question # 3 Answer
When put in certain solutions, an animal cell
could burst. What type of solution would
cause this?
Answer- Hypotonic
Question # 4
Explain the main difference between passive
and active transport.
Question # 4 Answer
Explain the main difference between passive
and active transport.
ANSWER- Passive transport requires NO energy
and moves molecules from high to low
concentration. Active Transport REQUIRES
energy and moves molecules against the
concentration gradient.
Question # 5
What occurs when a cell is put in an isotonic
solution?
Question # 5 Answer
What occurs when a cell is put in an isotonic
solution?
ANSWER- Molecules move across the cell
membrane in a process called DYNAMIC
EQUILIBRIUM. If 1 molecule moves in, 1 moves
out. If 3 move, 3 move out and so on.
Question # 6
Why do plants wilt in the summer?
Question # 6 Answer
Why do plants wilt in the summer?
ANSWER- There is a greater concentration of
water inside plants than outside, so in
effort to reach equilibrium the plant moves
water out of the plant cells causing the
cells to not be as stable.
Question # 7
What organelles are involved in endocytosis?
Question # 7 Answer
What organelles are involved in endocytosis?
ANSWER- The cell membrane folds inward
creating a VESICLE that then fuses with a
LYSOSOME, which helps to break down the
vesicle and it’s contents.
Question # 8- 2 points
In Day Two of the Egg Lab we put the egg in
corn syrup, what happened to the egg?
What type of solution is Corn Syrup?
Question # 8 Answer
In Day Two of the Egg Lab we put the egg in
corn syrup, what happened to the egg?
ANSWER- Water moved out of the egg bc of the
difference in concentration causing the egg
to shrink.
What type of solution is Corn Syrup?
ANSWER- HYPERTONIC
Question # 9- 2 points
What happened when the egg was placed in
distilled water?
What type of solution was the distilled
water?
Question # 9- 2 Answer
What happened when the egg was placed in
distilled water?
ANSWER- Water moved into the egg bc of the
difference in concentration causing the egg
to grow.
What type of solution was the distilled
water?
ANSWER- HYPOTONIC
Question # 10
There are two forms of endocytosis, what are
they?
Question # 10 Answer
There are two forms of endocytosis, what are
they?
ANSWER- Phagocytosis and Pinocytosis
Question # 11
What is the main difference between
Pinocytosis and Phagocytosis?
Question # 11 Answer
What is the main difference between
Pinocytosis and Phagocytosis?
ANSWER- Pinocytosis- process of taking liquid
into the cell by engulfing it in the membrane.
Phagocytosis- Type of endocytosis where cells
engulf large particle. Literally means “Cell
Eating”
Question # 12
How do nerve cells use active transport in
order to function correctly?
Question # 12 Answer
How do nerve cells use active transport in
order to function correctly?
ANSWER- Nerve cells require a higher
concentration of potassium than sodium, so it
pumps 3 Na atoms out for every 2 K atoms that
enter the cell.
Question # 13- 2 Points
What type of white blood cell aids the body
in fighting infections?
How does this process occur?
Question # 13- 2 Answer
What type of white blood cell aids the body
in fighting infections?
ANSWER- Macrophages
How does this process occur?
ANSWER- Occurs through the process of
Phagocytosis
Question # 14
How do transport proteins that are pumps
differ from those that are channels?
Question # 14 Answer
How do transport proteins that are pumps
differ from those that are channels?
ANSWER- Pumps require energy to move
molecules against a concentration gradient
and can change shape upon binding. Channels
do not change shape do not require energy.
Question # 15
Explain the difference between diffusion and
osmosis.
Question # 15 Answer
Explain the difference between diffusion and
osmosis.
ANSWER- Osmosis is the movement of only water
molecules from an area of high to low
concentration. Diffusion is the movement of
fluid or gas from an area of high to low
concentration.
