The cell membrane.
The cell membrane.
The structure you are referring to is the cell membrane, also known as the plasma membrane. It surrounds the cell, acts as a barrier, and regulates the passage of substances in and out of the cell through selective permeability.
The cell structure that forms the outer boundary of plant cells is the cell wall. It is a rigid, protective layer made up of cellulose that provides structural support and protects the cell from physical damage.
The cell membrane is the semipermeable structure in an onion epidermal cell. It regulates the passage of molecules in and out of the cell, allowing only certain substances to pass through while restricting others.
The Cell Membrane forms the outside boundary that separates the cell from its environment.
phospholipid bi-layer
The thin material that forms the boundary of the cell is called the cell membrane, or plasma membrane. It is primarily composed of a phospholipid bilayer with embedded proteins, which regulate the movement of substances in and out of the cell. This structure not only provides protection but also facilitates communication and signaling between cells.

In cells without cell walls, the cell membrane forms an outside boundary that separates the cell from its environment!
