The endomembrane system is composed of the different membranes that are suspended in the cytoplasm within a eukaryotic cell.These membranes divide the cell into functional and structural compartments, or organelles.he plasma membrane is a phospholipid bilayer membrane that separates the cell from its environment and regulates the transport of molecules and signals into and out of the cell. Embedded in the membrane are proteins that perform the functions of the plasma membrane.
Together, the total area of a cell's internal membranes far exceeds that of its plasma membrane. Like the plasma membrane, organelle membranes function to keep the inside in and the outside out.. This partitioning permits different kinds of biochemical reactions to take place in different organelles.f all eukaryotic organelles, the nucleus is perhaps the most critical. In fact, the mere presence of a nucleus is considered one of the defining features of a eukaryotic cell. This structure is so important because it is the site at which the cell's DNA is housed and the process of interpreting it begins.
