What is the effect on a cell when it is placed in a hypertonic solution?

When a cell is placed in a hypertonic solution, the concentration of solutes outside the cell is greater than the concentration of solutes inside the cell. This difference in concentration creates an osmotic gradient that causes water to move out of the cell in an attempt to equalize the solute concentrations. As water exits the cell, the cell loses volume and can eventually shrink or collapse. This process is known as crenation in red blood cells.

Understanding this concept is essential, as it highlights how cells interact with their environment through osmosis, impacting cellular functions and overall health. The cell's inability to regulate its internal environment in a hypertonic setting demonstrates the importance of maintaining proper osmotic balance for cellular integrity and function.
