WebA plant cell has a cell wall, a rigid structure located outside the plasma membrane, which encloses the cell. Plant cell walls can have up to three different layers—the middle lamella, primary cell wall, and secondary cell wall. Each layer incorporates polysaccharides—such as pectin, hemicellulose, and cellulose—as well as proteins. WebIn the cells of dicot plants, the primary wall consists of about 30 percent pectic polysaccharides; Consists of between 15 and 30 percent of cellulose; Contains about 20 percent of proteins; Secondary Cell Wall. As compared to the primary wall, the secondary cell wall is thicker and thus stronger ranging between 5 and 10um in thickness.
