The cell wall constitutes chemical compositions of the cell wall, they are primarily:
1) Matrix of the cell wall contains:
Water- 60%. Hemicellulose- 5-15%. Pectic substances- 2-8%.
Lipids- 0.5%-3.0%. Proteins- 1-2%.
2) Microfibrils in the cell wall contains:
Cellulose/fungus cellulose- 10-15%
3) Other Ingredients which contain in the cell wall:
Lignin, cutin, suberin, silica (silicon dioxide), minerals (example, iron, calcium, carbonate), waxes, tannins, resins, gum- in variable amounts or quantity.
CELL INCLUSIONS:
The cell inclusion found in the cells are some non living substances which are also called ergastic bodies. They may be present in soluble or insoluble state and can be organic or inorganic in their own nature. The cell inclusions belong to three categories- Reserve food, Excretory or secretory products an mineral matter.
