Explanation:

All cells have these four parts in common: a plasma membrane, cytoplasm, ribosomes, and DNA. Plasma membrane - also known as cell membrane. That's because all cells are surrounded by a structure called the cell membrane - which, much like the walls of a house, serves as a clear boundary between the cell's internal and external environments. The cell membrane is sometimes also referred to as the plasma membrane.
