Movement into and out of cells — practice question

Potato pieces of equal size were put into a test tube and then covered with a sucrose solution. The test tube was left for $30$ minutes, with every other variable kept constant. After $30$ minutes, the potato piece had stayed the same size. What can be concluded from this result?

  • AThe concentration of sucrose is the same in the potato and in the solution and there is no more movement of water into or out of the potato.
  • BThe concentration of sucrose is the same in the potato and in the solution and there is no net movement of water into the potato.
  • CThe water potential is the same in the potato and in the sucrose solution and there is no more movement of water into or out of the potato.
  • DThe water potential is the same in the potato and in the sucrose solution and there is no net movement of water into or out of the potato.
