hello,
--cell membrane is a living membrane having fine pores.
-- it is Semi permeable also called selectively permeable or differentially permeable ,meaning that it allows only certain substances to pass through while preventing others.
-- in Plant cell an additional outermost non-living layer called the cell wall surrounds the cell membrane.
-->functions of plasma membrane:
1. separates contents of cell from its surrounding.
2. regulates entry of certain solute and ions.
3. maintains shape of the cell ( in animal cell).
