Membranes are thin layers of organic material that form the outer boundary of cells and subcellular organelles within the cell They are selectively permeable, meaning that they can allow certain substances to pass through them while preventing the passage of others. This makes them an important part of the cell’s protective barrier, ensuring that only specific molecules appropriate for the wellbeing of the cell are able to enter. Membranes also serve other important roles within the cell, providing structure, acting as sites for enzyme reactions, and acting as channels for the transmission of signals across the membrane, among others.
