ii. Cellulose is a homopolymer made only of glucose and forms complex helical structures.
iii. Starch serves as an energy reserve in plants and can form helical structures that bind iodine, producing a blue color.
iv. Glycogen, found in animals, is a linear polysaccharide that does not have branches.
  • a)
    ii and iv
  • b)
    i and iii

Most Upvoted Answer
Which of the statements given above is/are correct?i. Polysaccharides ...
- Statement i is correct because polysaccharides can indeed be classified as homopolymers (like cellulose, which is made only of glucose) or heteropolymers (which contain different types of monosaccharides).
- Statement ii is incorrect; while cellulose is a homopolymer of glucose, it does not form complex helical structures. Instead, it has a linear structure that forms microfibrils.
- Statement iii is correct; starch serves as an energy reserve in plants and forms helical structures that can bind iodine, resulting in a blue complex.
- Statement iv is incorrect; glycogen is a highly branched polysaccharide, not linear, which allows for rapid mobilization of glucose when needed.
Thus, the correct statements are those in Option B: i and iii.
