Introduction
Cells are surrounded by thin membranes (approximately 5 nm) that separate inside from out, life from non-life. These cell membranes perform many functions:
·Barrier: membranes keep the contents of the cell together, allowing nutrients to pass in but keeping out many harmful substances.
·Signalling: membranes relays information about the surroundings of the cell tot eh inside and in the other direction
