Cell walls containing lignin are said to be lignifiided. Bacteria living in the spaces between the plant cells take up the opines and catabolize them (break them into components to use for growth). SUMMARY In order to maintain shape and withstand intracellular pressure, most bacteria are surrounded by a cell wall that consists mainly of the cross-linked polymer peptidoglycan (PG). The cell wall is a biphasic structure consisting of relatively rigid cellulosic microfibril embedded in gel-like non-cellulosic matrix. Such pits with borders are called bordered pits.Two opposite bordered pit are called bordered pit pair.Pits which lack the borders are called simple pits.Two opposite simple pits are called simple pit pair. cell wall is the most common topic for the science students and it is described with simple and to the point descriptions.

History While Robert Hooke’s discovery of cells in 1665 led to the proposal of the Cell Theory, Hooke misled the cell membrane theory that all cells contained a hard cell wall since only plant cells could be observed at the time. It is located outside the cell membrane and provides these cells with structural support and protection, in addition to acting as a filtering mechanism.  It is located outside the cell membrane and provides these cells with structural support and Bacteria living in the spaces between the plant cells take up the opines and catabolize them (break them into components to use for growth).
