Solution:

Polysaccharides
- Long chain polymers of monosaccharides. - Present in acid insoluble fraction.
- Examples :
1. Cellulose : It is a homopolymer with glucose as unit. Cellulose is found in cell wall of plants, algae, etc.
2. Starch : It is also a homopolymer of glucose. It serve as store house of energy in plant tissues.
3. Glycogen : It is a homopolymer of glucose. It serve as store house of energy in animals.
4. Inulin : It is a homopolymer of fructose.
5. Chitin : It is a complex homopolysaccharide made up of N-acetyl glucosamine (NAG). It is found in the exoskeleton of arthropods and cell wall of fungi.
6. Mucopolysaccharides : These are complex polysaccharides and heteropolymer of amino sugars and other chemically modified sugars.
