The barrier between the external environment and the inside of the cell is the cellular membrane, or just cell membrane. A cell wall is also present in plant cells, but substances can still enter through the cell wall. Harmful substances are stopped only when reaching the cell membrane. Some unicellular bacteria (or viruses) form an external layer outside the cell membrane, known as an envelope.

The Cell Membrane for an animal cell and a Cell Wall for a plant cell.
First of all it is does. And second a cell membrane acts as a barrier between the cell and its environment.
the cell membrane which is made up of a phospholipid bilayer.
Yes, the cell membrane forms a barrier with the outside environment. It is a selectively permeable membrane that regulates the movement of substances into and out of the cell, allowing some molecules to pass through while keeping others out. This helps to maintain the internal environment of the cell.
