Question

Protoplasm is a term coined for living parts of the cell ie. cytoplasm and nucleus. Cell Membrane is also a living membrane of the cell.Then why is it not included in protoplasm?

Answer 1

The proper definition of protoplasm is "the living content of the cell that is surrounded by cell or plasma membrane". Cell membrane is not a part of protoplasm, it is used to define the area covered by protoplasm.
