Coacervates are the large colloidal cell like aggregates of complex organic compounds. They are large enough to be seen under the microscope. In coacervates, lipid molecules are joined end to end forming a layer around each aggregate thereby representing a simple lipid membrane. Coacervates thus, represents the protocell model and an open system that keep accumulating materials from their environment.
The large orgainc molecules synthesize abiotically on primitive earth formed large colloidal aggregates or coacervates. Hence they are considered as primitive cell..
