Which of the following is a major component of biomass? (A) Cellulose (B) Ethanol (C) Natural gas (D) Oil - HSC - SSCE Chemistry - Question 2 - 2001 - Paper 1

Among the options provided, cellulose (A) is widely recognized as a major component of biomass. It is a polysaccharide that forms the structural component of the primary cell wall in green plants, algae, and the cell walls of bacteria.
