The definition of a cell membrane is a layer of tissue that surrounds a cell.
An example of a cell membrane is the protective layer around a skin cell.
The semipermeable membrane that encloses the cytoplasm of a cell. Also called cytomembrane . Also called plasmalemma . Also called plasma membrane .
The thin membrane that forms the outer surface of the protoplasm of a cell and regulates the passage of materials in and out of the cell. It is made up of proteins and lipids and often contains molecular receptors. The membranes of organelles within the cell are made of the same basic material as the cell membrane. In plant cells, the cell membrane is surrounded by a rigid cell wall. Also called plasma membrane

- They laid great stress on the nitrogenous nature of protoplasm, and noted that it preceded the formation of the cell-membrane.
- By the segmentation of the fertilized egg, now invested by cell-membrane, the embryo-plant arises.
- The cell-membrane may become modified by the process of lignification, suberization, cuticularization or gelatinization.

- The Nature of the Organization of Ilte Plant, and the Relations of the Cell-Membrane and the Protoplasm.This view of the structure of the plant and this method of investigation lead us to a greatly modified conception of its organization, and afford more completely an explanation of the peculiarities of form found in the vegetable kingdom.
