There are more than one kind of cell.
If it is an animal or bacteria cell, than the cell membrane separates it.
If it is a plant cell, than the cell wall separates it.

The barrier between the inside of a cell and its enviorment is a CELL MEMBRANE
The Cell Membrane for an animal cell and a Cell Wall for a plant cell.
The cell membrane acts as a barrier between a cell and its environment. This is composed of a phospholipid bilayer. The hydrophilic phosphate heads face outside and the hydrophobic lipid tails point towards each other in the centre of the membrane.

Cell membrane
Cell membrane acts as a barrier between the inside of a cell and its environment. It controls the movement of substances in and out of the cell to maintain internal conditions, allowing the cell to function properly. The cell membrane is selectively permeable, allowing only specific molecules to pass through.
cell membrane i hate science lol.
