Two groups of identical animal cells (internal solute concentration 0.25 M) are placed into separate solutions. Group X is placed in 0.25 M glucose; Group Y is placed in 0.25 M sucrose. The membrane is permeable to water and glucose but not to sucrose. After 15 minutes, Group X cells are larger than at the start, while Group Y cells show little change. Which outcome is most likely to explain why Group X swelled?
