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 'plasm…

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 c…

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.
