Cell membrane is also called the plasma membrane.
It can be observed only through an electron microscope.
Plasma membrane is the outermostcovering of the cell that separates the contents of the cell from its external environment.
Endocytosis
The plasma membrane is flexible and is made up of organic molecules called lipids and proteins.
The flexibility of the cell membrane also enables the cell to engulf in food and other material from its external environment. Such processes are known as endocytosis (endo → internal; cyto → of a cell). Amoeba acquires its food through such processes.
Diffusion
Plasma membrane is a selectively permeable membrane [The plasma membrane is porous and allows the movement of substances or materials both inward and outward].
Some substances like carbon dioxide or oxygen can move across the cell membrane by a process called diffusion[spontaneous movement of a substance from a region of high concentration (hypertonic solution) to a region where its concentration is low (hypotonic solution)].
Thus, diffusion plays an important role in gaseous exchange between the cells as well as the cell and its external environment.
Osmosis
Water also obeys the law of diffusion. The movement of water molecules through a selectively permeable membrane is called osmosis.
Osmosis is the passage of water from a region of high water concentration through a semi-permeable membrane to a region of low water concentration. Thus, osmosis is a special case of diffusion through a selectively permeable membrane.
Unicellular freshwater organisms and most plant cells tend to gain water through osmosis. Absorption of water by plant roots is also an example of osmosis.
Thus, diffusion is important in exchange of gases and water in the life of a cell. In additions to this, the cell also obtains nutrition from its environment.
Different molecules move in and out of the cell through a type of transport requiring use of energy in the form of ATP.
Reverse Osmosis (RO)
Reverse osmosis (RO) is a water purification technology that uses a semipermeable membrane to remove larger particles from drinking water.
In reverse osmosis, an applied pressure is used to overcome osmotic pressure.
Reverse Osmosis is a phenomenon where pure water flows from a dilute solution [hypotonic] through a semi permeable membrane to a higher concentrated solution [hypertonic].
Semi permeable means that the membrane will allow small molecules and ions to pass through it but acts as a barrier to larger molecules or dissolved substances.
