Once the freezing temperature enters a cell of the plant, that cell is kaput at least
in most tropical plants. However it takes a combination of low temperature and time
for that to happen. And it takes longer and more intensive cold for that to happen in
the petioles and even more in the more massive PS, than in the outer edges of the
leaves.
