What condition does hypertonic refer to in relation to cell environments?

Hypertonic conditions refer to environments where there is a higher concentration of solutes outside the cell compared to the inside. In this scenario, when a cell is placed in a hypertonic solution, water moves out of the cell in an attempt to balance the concentration of solutes on both sides of the cell membrane. As a result, the cell loses water and may shrink or crenate.

Understanding hypertonicity is crucial as it highlights the concept of osmosis—the movement of water across a semipermeable membrane in response to solute concentration differences. This principle is vital for applications in biology, such as understanding how cells maintain homeostasis and manage their internal environments.
