Detailed explanation-1: -Sucrose is not an example of polysaccharides.
Detailed explanation-2: -Sugar mainly contains monosaccharides and some disaccharides. Polysaccharides are not sugars. Thus, only statement III is incorrect.
Detailed explanation-3: –Cellulose, is a polysaccharide made up of 3, 000 or more units of glucose. Cellulose, the essential structural element of plant cell walls, constitutes about 33 percent of all plant material and is the most plentiful of all organic compounds that exist naturally. Thus, option B is not the correct option.
Detailed explanation-4: -Monosaccharides are converted into disaccharides in the cell by condensation reactions. Further condensation reactions result in the formation of polysaccharides.
