Introduction of Plant Cell Wall: A cell wall is a rigid (thick) layer of polysaccharides that are lying outside the plasma membrane of the plant’s cells, fungi, and bacteria. In the algae and higher plants, cell wall consists mainly of cellulose.Plant and bacterial cell membranes are enclosed by a thick cell wall.

Plant cell walls are three-layered structures with a middle lamella, primary cell wall and secondary cell wall. The middle lamella is the outermost layer and helps with cell-to-cell junctions while holding adjacent cells together (in other words, it sits between and holds together the cell walls of two cells; this is why it's called the middle

Subsequently, we learned that defined fragments of polysaccharides, released from covalent attachment within plant cell walls, can function as regulators of various physiological processes such as morphogenesis, rate of cell growth and time of flowering and rooting, in addition to activating mechanisms for resisting potential pathogens.

Plant cell walls are composed of structurally diverse polymers, many of which are O-acetylated. How plants O-acetylate wall polymers and what its function is remained elusive until recently, when two protein families were identified in the model plant Arabidopsis that are involved in the O-acetylation of wall polysaccharides – the reduced wall acetylation (RWA) and the trichome birefringence

Plant cell wall is composed of cellulose, hemicellulose, pectin and glycoproteins . Hemicelluloses (a heterogeneous group of polysaccharides) cross-link glycans interlocking the cellulose fibers and form a mesh like structure to deposit other polysaccharides.

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, UNLIKE ANIMAL CELLS, are surrounded by a rela- tively thin but mechanically strong cell wall. This wall consists of a com- plex mixture of polysaccharides and other polymers that are secreted by the cell and are assembled into an organized network linked together by both covalent and noncovalent bonds.

Plant Cell Wall. One of the most important distinguishing features of plant cells is the presence of a cell wall. The relative rigidity of the cell wall renders plants sedentary, unlike animals, whose lack of this type of structure allows their cells more flexibility, which is necessary for locomotion.

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.

The polysaccharide and glycoprotein components found in plant cell walls have been well characterized structurally. We need now to understand how these components are organized into the three-dimensional matrix needed for plant cell walls to perform their functions.

INTRODUCTION. The cells of plants are encased in a wall consisting of various polymer networks. One of the dominant components in the primary plant cell wall (i.e., the wall of growing cells) in dicots and nonpoacean monocots is the hemicellulosic polysaccharide xyloglucan (up to 30% dry weight) (Hayashi, 1989; Scheller and Ulvskov, 2010).
