The plant cell wall surrounds the plant cell as a complex network of polysaccharides classed as: cellulose, hemicelluloses and pectic polysaccharides and glycoproteins. Anchored to or embedded into plant cell wall are other polymers, like: lignin, suberin or cutin. Xylan is a group of hemicelluloses in plant cells walls and can also be found in some algae.
