And as it allow only selectively substance to pass the word. It is called as selectively permeable membrane as only selectively substance are getting penetrated inside at this pair are getting the entry inside at this bite is pollock select the copy of the so this is how we approach this question. To put it another way, biomembranes are enclosing membrane s which function as selectively permeable barriers to chemicals and ions. It should be noted though that the title biomembrane may denote a wide range of definitions; especially, cellular membranes should not be confused with isolating tissues formed by layers of cells (e.g., mucous membranes).

The main functions exerted by a biomembrane can be summarized as follows: (1) the membrane is a selective filter which controls the transport and the permeation of ions, molecular aggregates, and even large particles between the extracellular medium and the cytosol; (2) the membrane is the site for energy producing processes and for hormone signal transduction; (3) the membrane acts as receptor for extracellular signals and mediates the communications between intra- and extra-cellular media
