Factors affecting the structure of plasma membranes:

Temperature: The higher the temperature the more kinetic energy the phospholipds will have, they'll move about alot more and the bilayer structure will become more flexable. If the temp continues to increase the membrane will lose it's permeabilty. Also carrier and channel proteins will be denatured at higher temperatures their permeability will be affected.

Solvents: So, water is a polar molecule that interacts with the charged hydrophilic heads of the bilayer keeping the membrane intact. However many organic solvents are non-polar, meaning the hydrophilic surface of the membrane will break down and lose it's permeability. This is how alcohols (a non-polar solvent) work…
