If 0.9% NaCl is isotonic to a cell, it means that the concentration of solutes inside the cell is equal to the concentration of solutes in the 0.9% NaCl solution, leading to no net movement of water across the cell membrane. A solution with a higher concentration of solutes (1.0% NaCl) would be hypertonic relative to the cell, causing water to move out of the cell and potentially leading to cell shrinkage.

If 09% NaCl Were Isotonic to a Cell, Then
