A student investigated the effect of sodium chloride solution concentration on the water potential of sweet potato (Ipomoea batatas) cylinders.
For one sweet potato cylinder immersed in a high-concentration salt solution:
Calculate the percentage decrease in mass of this sweet potato cylinder.
Use the equation:
percentage decrease in mass=decrease in massinitial mass×100 \text{percentage decrease in mass} = \frac{\text{decrease in mass}}{\text{initial mass}} \times 100 percentage decrease in mass=initial 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.
