What are polysaccharides found in the cell wall called?
In plants and amoebas, the cell walls are made of cellulose. In fungi, they are made of chitin. Both are starches.
The materials in a cell wall can vary between species and in plants and fungi while also differ between cell types and developmental stages. In plants, the strongest component of the complex cell wall is the carbohydrate called cellulose, which is a polymer of glucose. In bacteria, peptidoglycan forms the cell wall. The Achaean cell walls have various compositions, and may be formed of glycoprotein S-layers, pseudopeptidoglycan, or polysaccharides. Fungi possess cell walls made of…
Cellulose is found on the cell wall of a plant cell. The "thick rigid structure" is due to the layers of polysaccharides (joined by many monosaccharides which formed glycosidic bonds, that makes them into a polysaccharide - process is called condensation reaction). This gives the cell wall the strength and stops it from bursting when too much water enters the cell.
