All living organisms are made up of cells. A cell has an outer wall or membrane that encloses a thick liquid which is called the cytoplasm. All the organelles of the cell except for the nucleus reside in the cytoplasm. In cells that have a nucleus it is surrounded by what is known as nucleoplasm and is separated from the cytoplasm.

The cytoplasm is made primarily of water, salts and organic molecules and has a mesh of protein strands that ensure the cell organelles stay in place. The cytoplasm acts as a medium in which all the exchange of ions and organic compounds between the other components of the cell takes place.

The protoplasm is a term used for everything that is contained within the cell membrane. This includes all the cell organelles as well as the cytoplasm
