In your own words
Sentence
Hypotonic Solution
• A solution or environment
surrounding a cell that has
less dissolved solutes and
more water than the cell
• This type of solution will
cause water to move into the
cell via osmosis, resulting in
swelling of the cell
Hypertonic Solution
• A solution or environment
surrounding a cell that has
more dissolved solutes
and less water than the
cell
• This type of solution will
cause water to move out
of the cell via osmosis,
resulting in shrinking of the
cell.
Isotonic
• A solution or
environment
surrounding a cell that
has the same amount
of dissolved solutes and
the same amount of
water as the cell

1. Read the articles and answer the questions
related to the article on a separate sheet of
paper.
Questions
1. What sort of environment (hypotonic, hypertonic,
isotonic) did the extra fertilizer create around the roots
of the corn?
2. Keeping in mind your answer to the previous question,
what do you believe caused the corn plants to wilt and
eventually die?
3. If Michael’s mistake had been caught earlier, is there
anything that could have been done to prevent the corn
from dying?
4. Generally, people water their plants with 100% H2O—no
solutes added. What sort of environment does this create
around the roots of the plant?
5. Briefly explain why plants generally thrive in this sort of
environment.
Questions
1. What problem did the distilled water in the
patient’s bloodstream create?
2. What happed to the patient’s blood cells as a
result?
3. Considering the function of red blood cells,
why did the patient’s oxygen levels fall?
4. After Tom made his error, is there anything
that could have been done to save the
patient’s life?
Membrane Transport skit
Objective: Create a skit that describes types of membrane
transport and how it help cells maintain homeostasis.
1. Use a cell membrane model or graphic to explain the
following:
a. Diffusion
b. Osmosis
c. At least one example of active transport (protein pump,
endocytosis, exocytosis)
2. For each of the transport methods above, give a specific
example of how this helps cells maintain homeostasis.
3. Each group member must participate in the creation of the
skit and appear in the skit.
4. You must turn in a copy of your skit to me before presenting
it to the class.
