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.
Prokaryotic cell
The cell is the fundamental , structural and functional unit of living organisms.
The prokaryotic cells which comprises the bacteria and blue green algae, lack a nuclear envelope in place of a membrane bound nucleus and nucleoid that remain in direct contact with the rest of the protoplasm. Cells that contain any true nucleys are called eukaryotic cells. Surrounded by plasma membrane, these cells have numerous intracellular compartments enclosed by membranes. These are called membrane bound organelles and include mitochondria and chloroplast.
Protozoa, most algae except Blue green algae, metaphyta and metazoa have eukaryotic cells. Prokaryotes are considered to be the ancestors of eukaryotes therefore in spite of differences between them both employ the same genetic code and have a similar mechanism for protein synthesis.
