Because the water is pure, the water outside will follow the concentration gradient of osmosis (from high concentration to low concentration). Since the percentage of solutes is much lower (in fact it's not even there in pure water) and the water concentration is much higher, ergo it'll flow into the cell to balance out the concentration. This causes the cell to swell, and eventually burst, or lyse.
