For what it's worth, current models for frozen animals and plants
don't have them freeze entirely. Their extracellular fluids do
indeed freeze solid, but the interiors of the cells are absolutely
loaded with antifreezes and antinucleating agents and can remain
fluid down to -40 and perhaps even lower.

That said, there are some Siberian trees whose tissues survive
freezing at much lower temperatures than that. ASAIK, nobody
has yet shown whether they have some super-antifreeze or
whether they just survive freezing.
