Answer 1

Answer:

Essay....

Plasma membrane is the membrane which controls the movements of substances and the ability of the cell to allow substances to pass in the interior of the cell while others do not .If the membrane was impermeable to all substances,then it could neither take the necessary substances for the survival of the cell ,nor to remove the useless substances that could maybe useful for other cells,especially when it come to multicellular organisms .If the membrane permeable to all substances it would also results to the entrance of substances harmful to the cells and would be difficult to maintain the correct concentrations of substances necessary for the cell because eventually the cell because of the phenomenon of diffusion would became one with the environment . The plasma membrane also regulates the recognition and reception or messages from outer and interior environment .The communication between cells seems to be served by a special class of lipids identified in cell membranes,the glycolipids .Thus, one more important function of the cell is the uptake and excretion of substances from the cell by creating outgrowths (pseudopodion) and indention.
