Cell membrane definition class 8. The plasma membrane of a cell is a network of lipids and proteins that forms the boundary between a cell’s contents and the outside of the cell. It is an additional covering over cell membrane. It gives shape and rigidity to these cells.

1)the cytoplasm and nucleus are enclosed within the cell membrane.it encloses the living part of the cell called protoplasm. A cell is always surrounded by a thin membrane called plasma membrane. It is, however, absent in animal cells.

The cell membrane is a multifaceted membrane that envelopes a cell's cytoplasm. 2)nucleus is the largest organelle in a cell. ‘cells are the basic structural units of living organisms’.

Definition it is the outer covering or boundary of cells other name it is also known as plasma membrane. The nucleus is a membrane based organelle that is found in eukaryotic cells. Cell membrane, also called plasma membrane, thin membrane that surrounds every living cell, delimiting the cell from the environment around it.
