I'm assigned an experiment to design on the subject of plant (edible)
oils. My teacher wants us to relate this to biology. My question is: what
do plants use for cold insulation? Do they use oils? If not, what prevents
them from freezing in colder places?
Plants avoid freezing either by a variety of mechanisms including
particular proteins, changes in osmotic pressure, supercooling, etc.
For edible oils:
