Which organism is made up of cells that have both a cell membrane and a cell wall?
Leokris [45]
Though most prokaryotes have both a cell membrane and a cell wall, there are exceptions such as Mycoplasma (bacteria) and Thermoplasma ( archaea ) which only possess the cell membrane layer. The envelope gives rigidity to the cell and separates the interior of the cell from its environment, serving as a protective filter. Hope this helped!
