Correct Answer - Option 3 : polysaccharide

The correct answer is a polysaccharide.

  • Starch is a polymeric carbohydrate consisting of numerous glucose units joined by glycosidic bonds.
  • Starch is a polysaccharide comprising glucose monomers joined in α 1,4 linkages.
  • The basic chemical formula of the starch molecule is (C6H10O5)n.
  • Starch is stored in chloroplasts in the form of granules and in such storage organs as the roots of the cassava plant; the tuber of the potato etc.

  • Monosaccharides are simple sugars in which there are one oxygen atom and two hydrogen atoms for each carbon atom present in the molecule.
  • They have general formula as (CH2O)n.
  • Disaccharides are made up of two monosaccharides joined together by a condensation reaction.
  • Polysaccharides are polymers formed by combining many monosaccharide molecules (more than two) by condensation reactions.
