Cellulose, polysaccharide nke mejupụtara monomers glucose nke β-1,4-glycosidic bonds jikọtara, bụ polima organic kachasị n'ụwa. A na-ahụ ya n'ime mgbidi sel nke osisi, ọ na-enye ike nhazi, na-eme ka osisi ruo n'ogo dị elu na akwụkwọ iji nọgide na-enwe ọdịdị ha. Owu, isi iyi eke kachasị ọcha nke cellulose, nwere ruo 90% nke polima a, ebe osisi na-enwekarị cellulose 40-50%, ya na lignin na hemicellulose. Algae na ụfọdụ nje bacteria na-emepụtakwa cellulose, na-agbasa nkesa okike ya.
