Understanding Solutions: Hypotonic, Isotonic, and Hypertonic

What happens to red blood cells when a hypotonic solution is introduced?

• They burst immediately.

• They swell as water enters the cells.

• They remain unchanged.

• They shrink due to water loss.

In an isotonic solution, how does the movement of water affect red blood cells?

• Water movement is completely stopped.

• Water moves equally in and out, keeping cells unchanged.

• Water moves only out of the cells.

• Water moves only into the cells.

Which type of solution causes red blood cells to maintain their normal shape?

• Hypertonic

• Hypotonic

• None of the above

• Isotonic

What is the primary characteristic of a hypertonic solution?

• It has more solutes than the cell.

• It has the same solute concentration as the cell.

• It has fewer solutes than the cell.

• It has no solutes at all.

How do red blood cells react to a hypertonic solution?

• They swell and burst.

• They shrink as water exits the cells.

• They remain unchanged.

• They dissolve completely.
