Plasma membrane .
The cell membrane is a organelles that is boundary between a cell and its environment.
The cell membrane, also known as the plasma membrane, provides a boundary between the internal and external environment of all cells. It is a semi-permeable barrier that regulates the passage of substances in and out of the cell, allowing for the maintenance of cellular homeostasis.
The Cell Membrane forms the outside boundary that separates the cell from its environment.
In cells without cell walls, the cell membrane forms an outside boundary that separates the cell from its environment!

Having a cell wall as the outermost boundary in a plant cell provides structural support and protection against mechanical stress. It also helps the cell maintain its shape and prevents bursting due to osmotic pressure. Additionally, the cell wall allows for greater resistance to pathogens and environmental stresses.
In cells without a cell wall, the outside boundary that separates the cell from its environment is formed by the cell membrane or plasma membrane. This phospholipid bilayer regulates the passage of molecules in and out of the cell, allowing for 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 phospholipid bilayer is located in eukaryotic cells as the main component of the cell membrane, which surrounds the cell and separates its internal environment from the external environment. It provides a semi-permeable barrier that controls the movement of substances into and out of the cell.
