cell membrane aka plasma membrane
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.
Methionine, a sulfur-containing amino acid, is an intermediary that helps strengthen cell membranes. The infamous cholesterol that we're often advised to avoid also helps maintain the integrity of cell membranes (and to a lesser degree, the integrity of the membranes of organelles inside the cell). The cell's plasma membrane is considered a fluid mosaic where the lipid molecules in the bilayer move about in the membrane. However, cell membranes may experience transitions which make their molecules more gel-like or nearly solid.
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.

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