Explanation:
Distilled water has no salts in it, so amoeba will swell up and burst, due to osmotic imbalance which is the phenomenon when the solute concentration is different in the medium and the cell. Every living cell requires an osmotically balanced medium, i. e. the salt concentration inside and outside it should be the same.
