Question
A cell is placed in an isotonic solution. How does the cell maintain homeostasis in this environment?
a
Water will move across the cell membrane to the inside of the cell because the cell has a higher concentration of solute particles than the solution.
b
There is no movement of water molecules into or out of the cell because the concentrations of solute particles inside and outside the cell are the same.
c
Water will move across the cell membrane to the outside of the cell because the solution has a higher concentration of solute particles than the cell.
d
Water will move across the cell membrane in both directions because the concentrations of solute particles inside and outside the cell are the same.

The correct answer is:
**d. Water will move across the cell membrane in both directions because the concentrations of solute particles inside and outside the cell are the same.**
In an isotonic solution, the concentration of solutes is equal inside and outside the cell, which means that there is no net movement of water. However, water molecules still move in and out of the cell simultaneously. This movement does not change the overall volume of the cell, allowing it to maintain homeostasis.
