WebThe plasma membrane—the outer boundary of the cell—is the bag, and the cytoplasm is the goo. Of course, a cell is ever so much more than just a bag of goo. It's a complex, highly organized unit, the basic building block … WebThe internal composition of the cell is maintained because the plasma membrane is selectively permeable to small molecules. Most biological molecules are unable to diffuse through the phospholipid bilayer, so the plasma membrane forms a barrier that blocks the free exchange of molecules between the cytoplasm and the external environment of the …
