Hint: Cell wall as the name implies is the protective covering or wall around the cells. Its components include lignin, cellulose, pectin, hemicellulose & many other proteins. Cell wall is found in Plants, Archaea, Fungi, Bacteria and Algae.
Complete answer:
Functions of different cell wall components are:
-Cellulose is the polymer of β-(1,4)-D-Glucose that provides strength to the plants along with maintaining the cell shape preventing the desiccation of cells.
-Hemicellulose is polysaccharide helps in strengthening the cell wall through interaction with cellulose and lignin
-Lignin is a complex polymer providing rigidity to the cell and tolerating many stresses in the wall.
-Pectin cements the cellulose & hemicellulose network, helps in plant defence and cell to cell adhesion.
-Plant cell proteins store Nitrogen, Carbon & Sulphur requirements in cell walls and plants.
Additional Information:
The primary functions of the cell wall include:
-Mechanical and structural support
-Tolerating turgor pressure
-Diffusion Regulation
-Protection & storage
-Communication
-Growth regulation
So, the correct answer is both (a) & (b)
Note:
-Cellulose is the most abundant macromolecule on earth.
-The human cannot digest cellulose.
-Cellulose is used to make clothes and paper.
