Q1Cotton fibre obtained from cotton seed is a:
Explanation
Cotton fibre is made mainly of cellulose, and cellulose is a polysaccharide built from many glucose units joined together. A monosaccharide is a single sugar unit such as glucose, so it is too small to describe cotton fibre. A polypeptide is a chain of amino acids and belongs to the protein family, not to carbohydrates like cellulose. A poly amino acid also refers to amino-acid polymers, again pointing towards proteins rather than the carbohydrate structure of cotton.
