Cellulose, wani polysaccharide wanda ya ƙunshi monomers na glucose da aka haɗa ta hanyar haɗin β-1,4-glycosidic, shine mafi yawan polymer na halitta a Duniya. Ana samunsa galibi a cikin bangon tantanin halitta na tsirrai, yana ba da tauri na tsari, yana ba bishiyoyi damar isa tsayi da ganye don kiyaye siffarsu. Auduga, tushen halitta mafi tsarki na cellulose, ya ƙunshi har zuwa 90% na wannan polymer, yayin da itace yawanci ya ƙunshi 40-50% cellulose, tare da lignin da hemicellulose.
