Questions and Answers

What is the primary consequence for a cell placed in an isotonic solution?

The cell's volume will remain stable. (correct)

The cell will swell and potentially lyse.

The cell will eventually shrink due to water loss.

The cell will divide into two daughter cells.

What is the essential condition for a solution to be considered isotonic?

The solute concentration outside the cell is higher than inside the cell.

The solutes can freely cross the membrane.

The solute concentration outside the cell is lower than inside the cell.

The solute concentration outside the cell is the same as inside the cell. (correct)

What will occur if a cell is placed in a solution where the solute concentration is the same as inside the cell but solutes can cross the membrane?

The cell will swell due to water gain.

The cell's volume will remain stable. (correct)

The cell will shrink due to water loss.

The cell will undergo apoptosis.

Study Notes

Isotonic Solution

A cell of a muscular well-built adult placed in an isotonic solution will experience no net flow of water into or out of the cell.
The cell's volume will remain stable in an isotonic solution.
An isotonic solution has the same solute concentration as inside the cell.
In an isotonic solution, solutes cannot cross the cell membrane.
