For an animal cell it is the cell wall. For a plant cell it is the cell membrane. In an animal cell the cell membrane is right inside the cell wall. The cell membrane is known as "The Gatekeeper" and is the main security of the cell.
Outer dynamic boundary is cell membrane. Outer boundary is cell wall
The outer boundary of a cell is called the cell membrane, and is composed of a phospholipid bilayer.
The outer boundary of a plant cell is the cell wall.
The outer boundary of an animal cell is the cell membrane.
The cell membrane makes the boundary of the cell. It is a lipid bilayer.
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 wall is similar to a protective barrier or fence surrounding a house. It provides structural support and protection to the cell, similar to how a fence provides boundary and security to a house.
Cell Membrane
The cell membrane is a organelles that is boundary between a cell and its environment.
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 outer boundary of all cells is the cell membrane but plant cells have a rigid cell wall outside the cell membrane.Cell Membrane forms the boundary that blocks most diffusion and allows regulation of the cell's internal conditions.
The Cell Membrane forms the outside boundary that separates the cell from its environment.
