Virus have no cells
The outer covering of an animal cell is the cell membrane. The outer covering of plant cells is the cell wall, which is much stronger and stiff.

cell membrane
It depends if the cell is an animal or plant cell. If it is an animal cell then the cell membrane is the outer boundary. If it is a plant cell then the cell wall is the outer boundary.
The cell membrane. It is a lipid bilayer with proteins integrated into it for transportation into and out of the cell.
cell membrane
The outer boundary of a general animal cell is the cell membrane.
Some have outer membrane, some don't. Gram positive bacteria - no outer membrane Gram negative bacteria - with outer membrane
The outermost structure of an animal cell is the cell membrane. The cell membrane is the membrane separating the interior of the cell from the outside environment. It is made up of proteins and lipids.
The outer boundary of a cell is called the cell membrane, and is composed of a phospholipid bilayer.
The outer coating of a cell is called the cell membrane. It is a thin, flexible barrier that surrounds the cell and controls the movement of substances in and out of the cell.
The outer layer of a cell is the cell membrane or plasma membrane
