Structure and Composition of Cell Membrane
Despite differences in structure and function, all living cells in multicellular organisms are surrounded by a cell membrane. Just like the outer layer of the skin separates the body from its environment similarly, the cell membrane, also known as 'plasma membrane,' separates the inner content from its exterior environment.
Cell Membrane
The cell membrane is known by different names like plasma membrane or cytoplasmic membrane, or biological membrane. The term "cell membrane" was first introduced by C. Nageli and C. Cramer in the year 1855. Later on, in 1931, the term "plasmalemma" for cell membrane was given by J. Plowe. The cell membrane separates the cell's internal environment from the extracellular space. This separation allows the protection of cells from their environment.
Prokaryotes vs Eukaryotes
The cell is defined as the basic structural and functional unit of life. The cell membrane bounds it. It is capable of independent existence.

A. head moves on the interphase array of microtubules, tail attached to vesicles, which move toward centrosome/center of cell
B. head moves on the interphase array of microtubules, tail attached to vesicles which move toward plasma membrane/away from center of cell
C. head moves along cortical actin, tail attached to vesicles which move toward plasma membrane
D. head moves along doublet microtubules of cilia/flagella, tail attached to neighboring doublet microtubules of cilia/flagella, the cilia/flagella bends or whips and causes cells to move
