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.
In some species, the calyx not only persists after flowering but instead of withering, begins to grow until it forms a bladder-like enclosure around the fruit. This is an effective protection against some kinds of birds and insects, for example in Hibiscus trionum and the Cape gooseberry. In other species, the calyx grows into an accessory fruit.

What can I do to protect bulbs from snow and freezing temperatures? You don't need to take any immediate action to preserve cold-damaged spring bulbs, according Iowa State University. Despite ...
The cold temperatures will bring widespread frost mainly after 3 p.m., according to NWS. Patchy fog could descend before 11 a.m. Saturday and will dissipate as temperatures are expected to rise to ...
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]
