What are the differences between cell membrane and cytoplasm?
Posted January 18, 2023

Answer

Basis of differentiation

Cell membrane

Cytoplasm

Definition
The cell membrane is defined as the double-layered phospholipids membrane which separates the interior of the cell from the external environment
The cytoplasm is defined as the jelly-like semifluid that enclosed by the cell membrane 
Function
Helps protect the cell and gives it its firm shape
Cytoplasm holds the cell organelles and acts as a reaction 
Separation from external environment
Cell membrane separates cells from one another and from the external environment
Cytoplasm doesn’t separate  cells from one another and from the external environment 
Stored and released energy
Energy is not stored or released in the cell membrane
Energy is stored and released in the cytoplasm 
Protoplasm
The cell membrane is not part of the protoplasm
The cytoplasm (as well as the nucleus) is part of the protoplasm
Movement of substances
The cell membrane has small pores that control the movement of different substances across the membrane
The cytoplasm is not responsible for the movement of various molecules across the cell membrane 
Cell adhesion and ion conductivity
The cell membrane is the primary site that is involved in cell adhesion and ion conductivity
The cytoplasm is not involved in cell adhesion and ion conductivity
