Plasma Membrane: Meaning, Structure and Functions.

The plasma membrane forms the boundary between the cell cytoplasm and the environment. Its function are to allow different environments to be established inside and outside the cell. It also controls the movement of substances into and out of the cell.The plasma membrane of a cell is a network of lipids and proteins that forms the boundary between a cell’s contents and the outside of the cell. It is also simply called the cell membrane. The main function of the plasma membrane is to protect the cell from its surrounding environment.The Function And Structure Of The Plasma Membrane - The overall purpose of the experiments in this lab was to introduce the function and structure of the plasma membrane, describe the workings of diffusion and osmosis, and to demonstrate how different factors such as particle size, temperature, and space of diffusion area affect the rate of diffusion.


Structure of Plasma Membranes The plasma membrane (also known as the cell membrane or cytoplasmic membrane) is a biological membrane that separates the interior of a cell from its outside environment. The primary function of the plasma membrane is to protect the cell from its surroundings.Functions of Plasma Membrane: Besides enclosing the cell and protecting it from the external environment, the plasma membrane has several important functions, such as, regulating the movement of materials inside and outside the cell, metabolic functions, communication between different cells and adhesion between cells.

The fluid mosaic model of plasma membrane is the most accepted hypothesis, which describes the membranous components and their functions. According to this model, the plasma membrane is similar to a fluid, in which various molecules are arranged in a mosaic-like pattern. The protoplasm of every living cell is enclosed by a plasma membrane.

Passive transport:. Passive transport is a type of diffusion in which ions and particles or molecules of various substances move through the plasma membrane from a region of higher to lower concentration by diffusion. How is the transport of molecules takes place in passive transport: Transport of molecules takes place along electrochemical or concentration gradient without consuming any.
