Question: what material comprises the cell wall of plants

title: Cell wall
text: The composition of cell walls varies between species and may depend on cell type and developmental stage . The primary cell wall of land plants is composed of the polysaccharides cellulose , hemicellulose and pectin . Often , other polymers such as lignin , suberin or cutin are anchored to or embedded in plant cell walls . Algae possess cell walls made of glycoproteins and polysaccharides such as carrageenan and agar that are absent from land plants . In bacteria , the cell wall is composed of peptidoglycan . The cell walls of archaea have various compositions , and may be formed of glycoprotein S - layers , pseudopeptidoglycan , or polysaccharides . Fungi possess cell walls made of the glucosamine polymer chitin . Unusually , diatoms have a cell wall composed of biogenic silica .
