Why does the potato in pure water (0 mol dm-3) gain mass?

Question

1. Because water has moved into the cells from where there is little water to where there is lots of water.
2. Because water has moved into the cells, from a high water concentration (in the beaker) to a low water concentration (in the cell). This is osmosis.
3. Because sugar has moved into the cells.
4. Because water has moved out of the cells, from where there is little water (in the cells) to where there is more water (in the beaker)

Answer 1
