Solution

The correct option is C Fischer
  • Protoplasm is a translucent living content of a cell enclosed by a plasma membrane.
  • It forms a crystallo-colloid type of solution because the protoplasm forms a mixture which contains a true solution of sugars, salts, acids and bases which forms the crystalloid part and proteins and lipids form the colloidal part.
  • Fischer proposed the crystallo-colloid theory of protoplasm which states that the protoplasm is a polyphasic colloidal system.
  • So, the correct answer is 'Fischer'.
