Tonicity in cells depends on both the concentration of solute outside the cell and the concentration of solute inside the cell
Tonicity is a concept used in biology that defines the osmotic pressure ( pressure that stops the fluids from entering or leaving cells). This pressure is defined by the concentration of solute (substances dissolved in the liquid) outside and inside the cell.
In this context, the cell is classified as isotonic if there is a balance between the concentration outside and inside; hypertonic if the concentration outside the cell is higher, which causes the cell to shrink of hipotonic if the concentration outside is lower, which causes the cell to swell.
