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 100 percentage decrease in mass=starting massdecrease in mass×10030 exam-style questions on AQA GCSE Biology 1.3 Transport in cells, covering 1.3.1 Diffusion, 1.3.2 Osmosis, and 1.3.3 Active transport.
