A cell in 1.5% NaCl is in a hypertonic solution .
For a cell to survive in its immediate environment, the movement of fluid is constantly being regulated.
The plasma membrane is selectively permeable and allows water and certain solute molecules to pass through it.
When a surrounding fluid and the cell contents have the same concentration, they are said to be isotonic. Example of such fluid is physiological saline that contains 0.9% NaCl.
When the fluid surrounding the cell is more concentrated (1.5% of NaCl) than the inside of the cell, it is said to be hypertonic.
Therefore the cell in 1.5% NaCl is in a hypertonic solution .
