Unformatted text preview: turgid . Hypertonic solution A hypertonic solution is one that has a high solute concentration. Cells in a hypertonic solution will lose water. The marine environment is a hypertonic solution for many organisms. They often have mechanisms to prevent dehydration or to replace lost water. Animal cells placed in a hypertonic solution will undergo crenation, a condition where the cell shrivels up as it loses water. Plant cells placed in a hypertonic solution will undergo plasmolysis , a condition where the plasma membrane pulls away from the cell wall as the cell shrinks. The cell wall is rigid and does not shrink. Left: These Elodea cells were placed in a 10% NaCl solution. The contents of the cells was reduced but the cell walls remained intact. Compare these cells to normal cells in the photograph below. Left: Normal Elodea cells X 400 ....
