    May 4, 2022 · Certain cells also produce a secondary wall that supports mechanically demanding processes, such as maintaining plant body stature and water transport inside plants. Both these walls are primarily composed of polysaccharides that are arranged in certain patterns to support cell functions.

    • Prokaryotic Cell Wall: a. Capsule: Some bacteria contain a capsule that surrounds their cell wall, and protects them from phagocytosis. The capsule layer is loose, gel like structure and can be observed by negative staining.
    • Plant Cell Wall: Eukaryotic plant cells are enclosed by a cell wall external to the plasma membrane. The cell wall provides rigidity, mechanical support to tissues and organs and gives a definite shape to the cell.
    • Animal Cell Glycocalyx: Animal cells are not enclosed by a cell wall. Instead they contain polysaccharide layers called glycocalyx on their surface.

    The cell wall structure has three layers; middle lamella, primary, and secondary cell wall. Middle lamella is the outer layer of the plant cell wall. It works as an interface between neighboring cells and attaches them. The layer has pectin, lignin, and some proteins.
