Chapter 3, Problem 2RE
Summary Introduction
To Determine:
If the given statement 'cells shrink in response to a hypertonic medium' is true or false should be determined.
Introduction:
A hypertonic solution refers to a specific kind of solution, which exhibits a higher concentration of solutes on the exterior of a cell when compared with the interior of a cell. In this case, the cells seems to be deprived of solutes.

Students have asked these similar questions
which of the following is a hypertonic solution (relative to body fluids)? Note: this can occur during a state of dehydration- 500mOsm, 100mOsm, or 300mOsm.
Soft contact lenses are made from hydrogels, which make them soft and flexible. It is important to
clean them daily using a sterile, isotonic cleaning solution. The concentration of solutes in the
cleaning solution is the same as the concentration of the hydrogel in the contact lens. What would
happen if instead of an isotonic cleaning solution, soft contact lenses are cleaned with water?
(A) The soft contact lenses will shrink because it will remove too much water by osmosis.
B The soft contact lenses will shrink because too much water is absorbed by osmosis.
The soft contact lenses will swell and change shape because too much water is absorbed
by osmosis.
The soft contact lenses will swell and change shape because too much water is removed by
osmosis.
When creating an artificial cell using a dialysis bag, how would you predict how the artificial cell will adjust to its immediate environment? Will it gain volume (hypotonoic), lose volume (hypertonic) or maintain the same volume (isotonic)?
