Question

Protoplasm of the cells is

• A. Colloid
• B. Suspension
• C. Emulsion
• D. None of the above

Answer 1

The correct option is A Colloid

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. Hence,Protoplasm of the cells is Colloid.
