The statement "All organisms contain prokaryotic cells" is not a fundamental idea of cell theory.

Cell theory generally includes the following key principles:

  1. All living organisms are composed of one or more cells.
  2. Cells are the basic unit of structure and function in living organisms.
  3. All cells arise from previously existing cells.

The statement about all organisms having prokaryotic cells is incorrect, as there are organisms composed of eukaryotic cells (like plants, animals, fungi, etc.) as well.
