Many textbooks will compare a cell membrane to the fluid mosaic model, which means that the parts of the membrane (phospholipids, cholesterol, proteins etc.) are not stuck in one place; they move around and can pass by one another while still keeping the integrity of the membrane. That is mainly for the structure, but structure always lends to function.

It's the plasma membrane. This is because it acts like a gate regulating what can enter and leave the cell. If the plasma membrane did not exist the cell would die because it might take in something that could kill it.
Cell membrane
A cell membrane is also known as a plasma membrane or cytoplasmic membrane. The cell membrane separates the interior of a cell from its outside environment. The main function of a cell membrane is to protect the cell from its surroundings.
the cell membrane is as flexible barrier outside of the cell.

There are multiple membranes in a cell. Two of them are the cell membrane and the nucleur membrane.
The outer boundary of a general animal cell is the cell membrane.

the cell membrane is the outer part of the cell wall.

cell membrane is the most outer part of a cell. cell membrane is very big in surface.
