  • The cytoplasm is a solution that surrounds the nucleus, and it contains the rest of the organelles that the cell needs for its functions.
  • The cell membrane is the structure that encloses all the cytoplasm and the nucleus. It is made of phospholipids, proteins, and cholesterol, which allows the passage of certain substances.
