plasma membrane
● plasma membrane or commonly known as Cell membrane act as a boundary to a cell.
● This membrane is also known as selectively permeable membrane because it allows the movement of only some type of substances and prevents the movement of others
● plasma membrane is formed of lipids and proteins that are generally synthesized in a cell.
● The main function of the plasma membrane is to form a boundary , give shape to a cell, inhibits the movement of some kind of substances, etc
. Proteins are very essential substances for a living organism are there involved in many processes like substance transportation, growth, etc . They also active enzymes and antibodies . Similarly lipids are also important for a cell. Their function is also notable for sustaining life.
● It is generally found as a bi layered structure. Movement of substances occurs through active transport, passive transport and by facilitated diffusion.
