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 * Factory site: membranes provides places where enzymes can be arranged in an assembly line fashion * Energy conversion: membranes allow light and chemical energy to be converted into more usable forms * Subdividing the cell: in most cells, membranes separate different parts of the cell which perform different functions * Recognition: different cell membranes have different surfaces and will interact differently with other cells. This allows cells to recognise one another and act accordingly; human cells...
