A solution with greater solute concentration than another is described as?

• A. Isotonic
• B. Hypertonic
• C. Hypotonic
• D. Osmosis

Answer: (B)

Tonicity describes how solute concentration compares between two solutions. When one solution has greater solute concentration than another, it is hypertonic relative to the other. Water moves by osmosis toward the hypertonic solution, so cells placed in it lose water and tend to shrink. In contrast, isotonic means equal solute concentrations with no net water movement, and hypotonic means lower solute concentration, causing water to enter cells and possibly swell. Osmosis is the process of water movement itself, not a description of a solution’s concentration.
