Question

How is temperature below zero degrees centigrade affect cell permeability

Answer 1

At temperatures below 0°C the phospholipids in the membrane don't have much energy and so they can't move much, which means that they're closely packed together and the membrane is rigid.

Answer 2

ExplanaGenerally, increasing the temperature increases membrane permeability. At temperatures below 0 o C the phospholipids in the membrane don't have much energy and so they can't move much, which means that they're closely packed together and the membrane is rigidtion:
