Biological membrane - Wikipedia
A biological membrane, biomembrane or cell membrane is a selectively permeable membrane that separates the interior of a cell from the external environment or creates intracellular compartments by serving as a boundary between one part of the cell and another.

Biomembrane - an overview | ScienceDirect Topics
Biomembranes are complex macromolecular assemblies that play a crucial role in maintaining life. They control molecular exchanges in a prominently aqueous cell medium by forming a boundary between an internal and external environment. Biomembranes can be found as an outer plasma membrane in both pro- and eukaryotes.
