Solution:
Cotton is obtained from the epidermal hair present on the surface of seeds of Gossypium sp. These are made up of cellulose only and may be of two types, ie, extractable lint and non-extractable fluffy fuzz. Cotton fibres are mainly used for textiles, celluloid, cellophane, rayon and paper pulp.
