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.

Enzymes are biological molecules that catalyze chemical reactions in cells. They are involved in a wide range of cellular processes, including metabolism, DNA replication, and protein synthesis.
Vesicles are membrane-bound sacs that transport materials within cells and between cells. They are involved in processes such as secretion, endocytosis, and exocytosis.
Lysosomes are membrane-bound organelles that contain enzymes responsible for breaking down and recycling cellular waste materials, such as proteins, lipids, and carbohydrates.
Golgi bodies, also known as the Golgi apparatus, are membrane-bound organelles that process and package proteins and lipids for transport to different parts of the cell or for secretion outside of the cell. They play an important role in the sorting, modification, and targeting of cellular materials.
