Origin of Cell Wall -

  1. The cell wall is product of cytoplasm.
  2. The cytoplasmic organelles such as endoplasmic reticulum, golgi apparatus play a very important role in the formation of cell wall.
  3. New cell wall develops at the time of cytokinesis.
  4. The cell wall formation is started by the formation of phragmoplast cell plate.
  5. At the time of cytokinesis a number of golgi body vesicles collect at the equator of the spindle.
  6. Vesicles (Phragmoplasts) fuse to produce cell plate.
  7. Cell plate grows centrifugally to divide parent cell into daughter cells.
  8. After deposition of Ca and Mg pactates, cell plate convert into middle lamella.
  9. In plants cell wall formed through centrifugal method.
  10. The formation of the middle lamella is also accompanied by some large vesicle known as phragmosomes & the vesicles of golgi apparatus which provide non cellulose material.
  11. Fibrils of cellulose are deposited on both sides of the middle lamella & formed the primary cell wall.
  12. The secondary cell wall develops later on by the deposition of cellulose, hemicellulose & pectin beneath the primary cell wall.
