The Cell membrane encompasses All Cells. It protects the Cell and controls what substances go in and out of It. So basically, It keeps all of the harmful products out of the Cell, and It lets good products come into the Cell.
Some Cells, such as plant Cells or fungi, have a Cell wall, which is different from a Cell membrane. Cell walls are on the outside of some Cells. They are a thick layer of nonliving material made of cellulose. They protect and support the Cell, and give Cells a rigid, box-like shape.
For animal Cells, since they don't have a Cell wall, the Cell membrane is the outer boundary that seperates the inside of the Cell from the environment around them. But for plant Cells, fungi, bacteria Cells, and other Cells with a Cell wall, the Cell membrane surrounds the Cell, but the Cell wall surrounds the Cell with the Cell membrane around it.

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.

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.

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.
