What is the strong material found in the cell walls of plants?
Cell wall The primary cell wall of land plants is composed of the polysaccharides cellulose, hemicelluloses 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 N-acetylglucosamine polymer chitin. Unusually, diatoms have a cell wall composed of biogenic
Cell wall associated kinase Cell wall associated kinase Cell wall associated kinases (WAKs) are receptor-like protein kinases, found in plant cell walls, that have the capability to transmit signals directly by their cytoplasmic kinase domains. They usually link the plasma membrane to the protein and carbohydrate that composed the cell wall. The receptor-like proteins contain a cytoplasmic serine threonine kinase and a less conserved region; bound to the cell wall and contains a series of epidermal growth factor repeats. WAKs are found in various plants and crops like rice, and maize. In plants genome like "Arabidopsis", WAKs, are encoded by five highly similar genes
