Movement into and out of cells — practice question

Two test-tubes, X and Y, were prepared, each containing the same volume of solution X or solution Y, respectively. A large number of type P cells and a large number of type Q cells were placed into test-tube X and also into test-tube Y. After a few minutes, samples of the solutions were removed and the cells were viewed using a microscope. In solution X, every cell of type P had burst, whereas cell type Q had not burst. In solution Y, none of the cells had burst. Which row correctly identifies cell type Q and solutions X and Y?

  • Acell type Q: red blood cells; solution X: 5% NaCl solution; solution Y: distilled water
  • Bcell type Q: goblet cells; solution X: 5% glucose solution; solution Y: distilled water
  • Ccell type Q: liver cells; solution X: distilled water; solution Y: 5% glucose solution
  • Dcell type Q: root hair cells; solution X: distilled water; solution Y: 5% NaCl solution
