Define the term: hypotonic solution.

A hypotonic solution is a type of solution that has a lower concentration of solutes compared to another solution, typically referring to the fluid inside a cell. When a cell is placed in a hypotonic solution, water moves into the cell through osmosis, causing the cell to swell and potentially burst.

Key Characteristics

• Lower Solute Concentration: The concentration of dissolved substances is less than that inside the cell.
• Water Movement: Water flows into the cell to balance solute concentrations.
• Cell Behavior: Cells may become turgid or even lyse (burst) if the difference is significant.

Examples in Biology

Common examples of hypotonic solutions include distilled water and certain saline solutions. These are often used in medical settings to hydrate cells or treat dehydration.

Importance in Cells

Understanding hypotonic solutions is crucial in biology and medicine, as it helps explain how cells interact with their environment and maintain homeostasis.
