Complete the following scenarios on osmosis, movement of water.
A red blood cell (0.9% NaCl) is placed into a solution of 20%
NaCl. The water is able to mov through the cell membrane, what
happens to the red blood cell in this situation? Is this
environment (outside solution) that the cell was placed into
hypertonic or hypotonic?
A red blood cell (0.9% NaCl) is placed into a solution of 100%
DI water. The membrane is again permeable to water. What happens to
the cell in this situation? Is this environment (outside solution)
hypertonic or hypotonic?
A plant cell (0.9% NaCl) is placed into a solution of 20% NaCl,
the membrane is permeable to water. What happens to the plant
cell?
A plant cell (0.9% NaCl) is placed into a solution of 100% DI
water, the membrane is permeable to water. What happens to the
plant cell?
5 A dialysis bag (simulating a membrane) of 15% glucose is
placed in a beaker of 5% glucose. The bag is permeable to
both water and glucose.
A. What is the net movement of
water?
B. What is the net movement of
glucose?
C. Which solution in this situation
s hypertonic and which is hypotonic?
