biological process
    GO:0071555    cell wall organization    A process that results in the assembly, arrangement of constituent parts, or disassembly of the cell wall, the rigid or semi-rigid envelope lying outside the cell membrane of plant, fungal and most prokaryotic cells, maintaining their shape and protecting them from osmotic lysis.
    GO:0009252    peptidoglycan biosynthetic process    The chemical reactions and pathways resulting in the formation of peptidoglycans, any of a class of glycoconjugates found in bacterial cell walls.
    GO:0008360    regulation of cell shape    Any process that modulates the surface configuration of a cell.
