a CELL WALL It is the nonliving rigid structure which forms the outer covering for the plasma membrane of fungi and plantsCell wall not only gives shape to the cell and protects the cell from mechanical damage and infectionIt also help helps in celltocell interaction and provides barrier to undesirable macromolecules The cell wall of a young plant cell which is the primary wall is capable of growth which gradually diminishes as the cell matures and the secondary wall is formed on the inner side of the cellThe middle lamella is a layer mainly of calcium pectate which holds the different neighboring cells together The cell wall and the middle lamella may be traversed by plasmodesmata which connects the cytoplasm of neighboring cells bPLASMA MEMBRANE Plasma membrane is made up of lipids that are arranged in a bilayer Also the lipids are arranged within the membrane with the polar head towards outside and the Hydrophilic tail towards the inner partOne of the most important function of the plasma membrane is the transport of molecules across it The membrane is    See Answer
