Abstract : Studies of the mechanism of freezing injury in living cells have resulted in the development of an hypothesis that freezing injury results from osmotic dehydration and volume reduction of cells as extracellular water is frozen out. Regardless of composition, the loss of approximately 65% of animal cell liquid leads to cell damage, while plant cells show a similar limiting dehydration at about 55%. A discussion is made of the osmotic dehydration process.
