IN THE ACTIVITY OF ONION PEEL (WHICH CONTAINS PLANT CELLS) IT IS GIVEN THAT THE CELL IS SURROUNDED BY PLASMA MEMBRANE ,BUT AFTER A FEW LINES IT IS WRITTEN THAT "In plant cells, the outermost covering also constitutes the cell wall, beneath which the plasma membrane lies.".
HOW IS IT POSSIBLE
Plasma membrane is the immediate layer that surrounds all the cells and it is surrounded by a cell wall in case of plant and bacterial cells.
