    The structural complexity of the plant cell wall arises in part due to the variety of polysaccharides used to assemble this organelle, the spatial and temporal separation of their synthesis, and the various chemical modifications that occur within these polysaccharides. Cell wall polysaccharides are often grouped into three functional categories: cellulose, hemicelluloses, and pectins. Cellulose is composed of 30–40 β-(1 → 4)-linked glucan chains that associate to produce semi

    Plant cells are surrounded by a strong polysaccharide-rich cell wall that aids in determining the overall form, growth and development of the plant body. Indeed, the unique shapes of the 40-odd cell types in plants are determined by their walls, as removal of the cell wall results in spherical protoplasts that are amorphic.
