A student investigated the water potential of plant tissue by placing cylinders of parsnip (Pastinaca sativa) into various concentrations of sucrose solution.
For one cylinder placed in a hypertonic solution:
Calculate the percentage decrease in mass of this parsnip cylinder.
Use the equation: percentage decrease in mass=decrease in massstarting mass×100\text{percentage decrease in mass} = \frac{\text{decrease in mass}}{\text{starting mass}} \times 100percentage decrease in mass=starting massdecrease in mass×100
