Cell wall. Many types of prokaryotic and eukaryotic cells have a cell wall. The cell wall acts to protect the cell mechanically and chemically from its environment, and is an additional layer of protection to the cell membrane. Different types of cell have cell walls made up of different materials; plant cell walls are primarily made up of cellulose, fungi cell walls are made up of chitin and bacteria cell walls are made up of peptidoglycan.
The mononuclear phagocyte system (MPS) (also called Reticuloendothelial System or Macrophage System) is a part of the immune system that consists of the phagocytic cells located in reticular connective tissue.The cells are primarily monocytes and macrophages, and they accumulate in lymph nodes and the spleen.he spleen is the largest unit of the mononuclear phagocyte system. The monocyte is formed in the bone marrow and transported by the blood; it migrates into the tissues, where it transforms into a histiocyte or a macrophage.
