Movement into and out of cells — practice question

Diagram 1 and diagram 2 illustrate how the transverse section of a leaf is altered when the leaf is transferred from solution X to solution Y. Which row gives the water potential of the leaf cells and the surrounding solutions in diagram 2 compared with diagram 1?

  • Aleaf cells: less negative; solution Y compared with solution X: less negative
  • Bleaf cells: less negative; solution Y compared with solution X: more negative
  • Cleaf cells: more negative; solution Y compared with solution X: less negative
  • Dleaf cells: more negative; solution Y compared with solution X: more negative
