Plasma Membrane Definition
Plasma membrane can be defined as a biological membrane or an outer membrane of a cell, which is composed of two layers of phospholipids and embedded with proteins . It is a thin semi permeable membrane layer , which surrounds the cytoplasm and other constituents of the cell.
Function of Plasma Membrane
1 . It separates the contents of the cell from its outside environment and it regulates what enters and exits the cell.
2 . Plasma membrane plays a vital role in protecting the integrity of the interior of the cell by allowing only selected substances into the cell and keeping other substances out.
3 . It also serves as a base of attachment for the cytoskeleton in some organisms and the cell wall in others. Thus the cell membrane supports the cell and helps in maintaining the shape of the cell.
4 . The cell membrane is primarily composed of proteins and lipids. While lipids help to give membranes their flexibility and proteins monitor and maintain the cell' s chemical climate and assist in the transfer of molecules across the membrane .
5 . The lipid bilayer is semi-permeable , which allows only selected molecules to diffuse across the membrane .
Characteristics of Plasma Membrane
Below you could see characteristics of plasma membrane
1 . The plasma membrane (cell membrane ) is made of two layers of phospholipids.
2 . The plasma membrane has many proteins embedded in it .
3 . The plasma membrane regulates the entry and exit of the cell. Many molecules cross the cell membrane by diffusion and osmosis .
4 . The fundamental structure of the membrane is phospho lipid bilayer and it forms a stable barrier between two aqueous compartments.
5 . The proteins present in the plasma membrane, act as pumps , channels , receptors, enzymes or structural components .
Plasma Membrane Structure
1 . It is the boundary, which separates the living cell from their non - living surroundings.
2 . It is the phospholipids bilayer .
3 . Plasma membrane is an amphipathic , which contains both hydrophilic heads and hydrophobic tails .
4 . It is a fluid mosaic of lipids, proteins and carbohydrate .
5 . It is lipid bilayer, which contains -two layers of phospholipids, phosphate head is polar ( water loving ) , fatty acid tails non -polar (water fearing ) and the proteins embedded in membrane.

hai sisi
here is your answer
-> cell membrane or plasma membrane is made of protein and lipids
function:
-> it gives shape to the cell
-> gives protection to the cell
-> separates the inner contents of the cell from external environment
-> helps in entry and exit of certain substances.
-> this property of cell membrane is called as ' SEMI PERMEABILITY OR SELECTIVE PERMEABILITY.
-> it helps in maintaining the volume of the cell
hope it helps you
