Cold hardening
Cold hardening (pronunciation: /koʊld ˈhɑːrdnɪŋ/) is a physiological process in which an organism prepares for cold weather.
Etymology
The term "cold hardening" comes from the English words "cold", referring to low temperatures, and "hardening", which refers to the process of becoming more resistant or robust.
Process
Cold hardening involves a series of physiological and biochemical changes that allow an organism to survive in freezing temperatures. These changes can include the production of antifreeze proteins, changes in cell membrane composition, and the accumulation of certain solutes that help to prevent freezing.
Related Terms
- Antifreeze proteins: Proteins produced by certain organisms that inhibit the formation of ice crystals, thereby preventing damage to tissues at freezing temperatures.
- Cell membrane: The semipermeable membrane surrounding the cytoplasm of a cell, changes in its composition can help the cell to survive in freezing temperatures.
- Solute: A substance that is dissolved in a solution. In the context of cold hardening, certain solutes can help to prevent freezing.
