Question

which term refers to a solution with a higher solute concentration outside the cell than inside the cell?
hypertonic
hypotonic
equitonic
isotonic

Explanation:

• A hypertonic solution has a higher solute concentration outside the cell compared to inside. This causes water to move out of the cell (osmosis) to balance the concentration gradient.
• A hypotonic solution has a lower solute concentration outside the cell, so water moves into the cell.
• "Equitonic" is not a standard term in this context.
• An isotonic solution has equal solute concentrations inside and outside the cell, with no net water movement.

Answer:

A. hypertonic
