Question

What do ypu mean by plasma membrane . Describe the structure and different models of plasma membrane?

Answer 1

hi mate..

it is cell in closed membrane that separate the cytoplasm from external environment called cell plasma or plasma membrane .
it is consist of phospholipid protein and cholesterol and little amount amount of carbohydrate
the only model which soil of fluid mosaic model which is proposed by singer and nicolson in 1972
according to this model a liquid by layer is written as a core of membrane the liquid molecules are present in fluid state capital of rotating and moving with in the membrane structure and arrangement of membrane protein in this model like a Iceberg in AC that pretty associate with Leopard Balia can be divided into two groups
INTEGERAL
they are directly incorporate meaning in the Leopard Valley they provide channel for waste dissolving substance
EXTRINSIC
this protein located outside or inside the lipid bilayer exhibit loose Association with membranes surface
the important function of plasma membrane is to protect the cytoplasm and regulate the flow of substance from maintaining suitable PH and concentration enzyme activity substance from the body by the help of diffusion and osmosis.
hope it is helpful for you.
please mark me as brain list
have a great ahead

Plasma membrane, Also known as Cell Membrane is a thinnest covering of an living organism.

For example:- A thinest covering of an onion.

View the attachment.

The fluid mosaic model describes the structure of a plasma membrane as a mosaic of components including: Phospholipids, Cholesterol, Proteins and Carbohydrates that gives the membrane a fluid character. Plasma membranes ranges from 5 to 10 nanometres in thickness…

For example:- Myelin contains 18% Protein and 76% Lipid.
