Textbook Question
Chapter 6, Problem 2TYK
If a solution surrounding a cell is hypertonic relative to the inside of the cell, how will water move?
a. It will move into the cell via osmosis.
b. It will move out of the cell via osmosis.
c. It will not move, because equilibrium exists.
d. It will evaporate from the cell surface more rapidly.

A. water will move into the cell
B. nothing
C. its volume will fluctuate up and down
D. water will leave the cell
E. sugar will move into the cell
What is osmosis?
a.
the process where water diffuses across the cells' membrane from an area of lower water concentration to an area of higher water concentration
b.
Where a solute diffuses across the cell membrane from an area of higher to lower concentration
c.
the process where water diffuses across a cells' membrane to an equal concentration of water on both sides of the membrane
d.
The process where a solute diffuses into water through membranous sacks not using energy
