Plants are comprised of different particular cell types that contrast in their cell wall arrangement and structure. The cell walls of specific tissues like xylem sclerenchyma are portrayed by the occurrence of cellulose and the heterogeneous lignin polymer all of which assumes a noteworthy role in the physiology plant growth and for the sustainable economic purposes like bioethanol production. By far most of plant biomass comprises of various cell wall polymers created by living plant cells. The greater part of these polymers are vitality rich connected sugars that shape the major auxiliary system in plant cell walls, especially in the thick secondary cell wall describing certain tissues. Notwithstanding cell wall polysaccharides, another critical cell wall biopolymer is lignin restricting the access to cell wall sugars Because of its huge financial effect and pivotal job in vascular plant advancement; lignification is an imperative topic in plant biochemistry. So it is really important to understand the intricate network of secondary cell wall components and their biosynthesis which will be the major highlights for discussion in this review.
