Question :-

Write a detailed info on cell membrane or plasma membrane.

Answer :-

Cell membrane or plasma membrane is a thin, delicate membrane surrounding the cytoplasm . The cell membrane of plasma membrane perform the following functions :-

● It separate the cells from one another and also separates the cell from the surrounding medium .

● It gives a definite shape to the cell .

● Being porous, it allows the movements of substances from both inside or outside the cells .

● Its porous structure help in regulating the movement of materials through the cells .

In addition to the cell membrane, there is an outermost thick layer in plant cell called cell wall which is made up of non-living and a rigid substances called the cellulose. This additional layer surrounding the cell membrane is required by the plant cell for its protection against temperature variations, atmospheric moisture and high speed winds. Plants cells need protection because they are unable to move from their place in such situation. The cell wall also provide rigidity to the plant cells .
