The cytoplasm of the red blood cell contains dissolved salts and sugars. Since the cytoplasm of the red blood cell has a higher concentration than the distilled water, there is net flow of water into the cell by osmosis. The cell would swell up and eventually burst. The bursting of a red blood cell is known as haemolysis.
OR
Red blood cells absorb water by osmosis;they swell the cell membrane bursts/cell haemolysed.
