Cryopreservation in Nature
Many living organisms are able to tolerate prolonged periods of time at temperatures below the freezing point of water. Most living organisms accumulate cryoprotectants such as anti-nucleating proteins, polyols, and glucose to protect themselves against frost damage by sharp ice crystals. Most plants, in particular, can safely reach temperatures of −4 °C to −12 °C.

Famous quotes containing the word nature:
“God alone is our true good, and since we have forsaken him, it is a strange thing that there is nothing in nature which has not been serviceable in taking his place: the stars, the heavens, earth, the elements, plants, cabbages, leeks, animals, insects, calves, serpents, fever, war, famine, vices, adultery, incest.”
—Blaise Pascal (1623–1662)
