    Acid-Fast cell walls (mycolic acid), mycoplasmas (lack cell wall), Archaea (wall-less).
  39. What is Protoplast?
    A wall-less cell
  40. What is a spheroplast?
    A wall-less gram-positive cell
  41. What are L forms, in Damaged Cell wall?
    Wall-less cells that swell into irregular shapes.
  42. What is selective permeability?
    It allows passage of some molecules.
