The egg will lose water and shrink.

Detailed explanation-1: -An egg with a dissolved shell is placed in pure water for 48 hours. Water will move in and out of the cell equally, and the cell with neither shrink nor swell. The egg will gain water and swell.
Detailed explanation-2: -Giving large amounts of pure water directly into a vein would cause your blood cells to become hypotonic, possibly leading to death.
Detailed explanation-3: -If a cell is placed in a hypertonic solution, water will leave the cell, and the cell will shrink. In an isotonic environment, there is no net water movement, so there is no change in the size of the cell. When a cell is placed in a hypotonic environment, water will enter the cell, and the cell will swell.
Detailed explanation-4: -The rain water is hypertonic to the cells so the cells lose water. They have cell walls that keep them from swelling too much.
Detailed explanation-5: -Because the water outside the root cells has a lower salt concentration, water starts moving into the root cells due to osmosis. The water entering the plant fills up the cells and can travel to the rest of the plant.
