a plasma membrane
All cells have a cell membrane! Only "plant cells" have a cell wall, and a cell membrane!
depend on the kind of cell...... plant: cell wall and cell membrane/plasma membrane animal: cell membrane/plasma membrane
Called a prokaryotic cell.

Plant Cells
The cell membrane, or plasma membrane, regulates the passage of materials into and out of cells through selective permeability. This means that only certain substances are allowed to pass through the membrane, while others are blocked or actively transported. This selective permeability helps maintain the internal environment of the cell and allows for proper function and communication with the external environment.
That kind of membrane in cells is called a mosaic membrane since the molecules are not all the same.
