  2. Cryoprotectant - Wikipedia

    en.wikipedia.org/wiki/Cryoprotectant

    A cryoprotectant is a substance used to protect biological tissue from freezing damage (i.e. that due to ice formation). Arctic and Antarctic insects, fish and amphibians create cryoprotectants (antifreeze compounds and antifreeze proteins) in their bodies to minimize freezing damage during cold winter periods. Cryoprotectants are also used to ...

    In temperate regions of the southern hemisphere, where seasonal cold temperatures are not as extreme or long lasting, freeze tolerance is more common. [2] However, in the Arctic , where freezing occurs seasonally, and for extended periods (>9 months), freeze tolerance also predominates.

  8. Freezing tolerance - Wikipedia

    en.wikipedia.org/wiki/Freezing_tolerance

    The ability to control intercellular ice formation during freezing is critical to the survival of freeze-tolerant plants. [3] If intracellular ice forms, it could be lethal to the plant when adhesion between cellular membranes and walls occur. The process of freezing tolerance through cold acclimation is a two-stage mechanism: [4]
