3 Extreme Ways Trees Survive the Winter

The video explores how living organisms, particularly trees, adapt to survive in freezing temperatures. It explains the process of extracellular freezing, where ice forms between cells, and supercooling, which prevents dehydration. The video also discusses vitrification, a process where tree cells turn into glass to withstand extreme cold. These adaptations allow trees to survive temperatures as low as -40°C and even lower in some cases.

What happens to tree cells when temperatures drop below -40 degrees Celsius?

Describe the process of vitrification in trees and its significance.

How do sugars and dehydrins contribute to the survival of trees in extreme cold?
