Osmosis — practice question

The data present the findings from an investigation into osmosis using pieces of potato. The concentration of sugar solution is $0.6\ \text{mol per dm}^3$. The potato stick measures $60\ \text{mm}$ at the beginning and $54\ \text{mm}$ after $24$ hours. Which statements account for this change in length?

  • Amovement of water into the potato cells; the sugar solution has a higher water potential than the potato cells
  • Bmovement of water into the potato cells; the sugar solution has a lower water potential than the potato cells
  • Cmovement of water out of the potato cells; the sugar solution has a higher water potential than the potato cells
  • Dmovement of water out of the potato cells; the sugar solution has a lower water potential than the potato cells
