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]
There is a rapid cold hardening capacity found within certain insects that suggests not all insects can survive a long period of overwintering. Non-diapausing insects can sustain brief temperature shocks but often have a limit to what they can handle before the body can no longer produce enough cryoprotective components. The common fruit fly
Woody plants survive freezing temperatures by suppressing the formation of ice in living cells or by allowing water to freeze in plant parts that are not affected by ice formation. The common mechanism for woody plants to survive down to –40 °C (–40 °F) is supercooling. Woody plants that survive lower temperatures are dehydrating their ...
It can also survive without problems in a pot, where it is grown in hanging baskets so the long trailing branches can hang down with their leaves spaced out. Over-wintering should take place in a frost-free, sunny place at approximately 5 to 8 °C (41 to 46 °F). No serious insect or disease problems are known.

As a succulent plant, Kalanchoe daigremontiana can survive prolonged periods of drought with little or no water. During growth periods with higher temperatures and increased water supply, this species requires proper nutrition, without which leaves show deficiency symptoms such as crippled growth and pustule-like lesions.
Cockroach nymphs (Periplaneta japonica) survive short periods of freezing at -6 to -8 °C. The red flat bark beetle ( Cucujus clavipes ) can survive after being frozen to -150 °C. [ 6 ] The fungus gnat Exechia nugatoria can survive after being frozen to -50 °C, by a unique mechanism whereby ice crystals form in the body but not the head.
In order to maintain performance across a range of environmental conditions, there are several strategies organisms use to acclimate. In response to changes in temperature, organisms can change the biochemistry of cell membranes making them more fluid in cold temperatures and less fluid in warm temperatures by increasing the number of membrane proteins.
