Solution:

Polysaccharides (type of carbohydrates) comes under the class of macromolecules. Macromolecules form the part of retentate (acid insoluble fraction) when a living tissue is treated with trichloroacetic acid. Polysaccharides form long chains of sugars made by joining same or different monosaccharides together. Cellulose is a polysaccharide having more than 10 units of only one type of monosaccharide - glucose. In a polysaccharide chain (say glycogen), the right end is called the reducing end and the left end is called the non-reducing end as the right end cannot reduce oxidizing agents. Thus, only statement 2 is incorrect.
