Why do cells have a plasma membrane? to distinguish plants from animals

to define the size of the cell

to separate the inside of the cell from its environment

to separate proteins from the nucleus

to separate the inside of the cell from its environment

If cells did not have a plasma membrane, they would die. The parts/organs that keep them alive will leak out everywhere. Since cells are basic building blocks for humans, if they died, we would die.

Hope this helps you!
