Recognition that cell walls are not rigid but that they are instead metabolically active and responsible for expansive cell growth and differentiation occurred some 200 years later (Sachs, 1887). Algal cell walls are composed of a diverse array of fibrillar, matrix and crystalline polymers interacting with various ions and water. In addition, algal cell walls have mannans, xylans, alginic acid and sulfonated polysaccharides. Algal cell walls contain either polysaccharides (such as cellulose (a glucan)) or a variety of glycoproteins (Volvocales) or both. It is a hydrophilic, Crystalline, compound polysaccharide. Walls consisted mainly of polysaccharide with lesser quantities of associated protein and lipid. In a general sense, the main material in a Plant cell wall is cellulose, which is undigested by a lot of animals that might eat plants.
