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.
The rough endoplasmic reticulum is embedded with what
Introduction:- Eukaryotic cells consist of various kind of membrane bound cell organelles, these include - Nucleus, mitochondria, chloroplast ( in plants), endoplasmic reticulum, Golgi apparatus, lysosomes etc. These cell organelles helps in the independent existence of a single cell ( as in the case of unicellular organisms). They perform different functions, like - nucleus contains the genetic material and thus controls genetics & inheritance, mitochondria is the place where synthesis of ATP takes place, and chloroplast is the site of photosynthesis.
