The passage of certain substances through the membrane
The cell membrane, which is a lipid bilayer, will only allow some things in and allow others to go out of the cell.
It is the ability of the membrane to allow ions and/or particles to cross.
The cell membrane is the thing that surrounds the cell. The cell membrane contains proteins that allow active transport of molecules in and out of the cell.
The cell membrane of a cell with low mass would be better able to feed all the cytoplasm of the cell. This is because a thinner membrane would allow for more efficient transport of nutrients and waste products in and out of the cell.
The cell membrane is somewhat of an environment.. cell membranes have many proteins inside them.. the proteins regulate the cell structure, allow cell-cell interaction, and allow passage of materials through the membrane. There also steroids in the membrane that regulate its shape.. and there are also various sugars / glycoproteins in the membrane. Also, one important thing to realize is that the inside of the cell membrane is NON polar.. the outside is polar however.

The Cell membrane on a plant cell is used to allow some substances into the cell (for nourishment) while keeping other (harmful or unwanted) substances out.
