The cellulose is flexible and allows cells to increase in size. the provides considerable strength for the plant cell. the main component of the cell wall is lignin. in plants, is a metabolite that hardens the wall. plant cell wall polysaccharides are made of repeating molecules.

The secondary cell wall provides considerable strength for the plant cell. The main component of the cell wall is lignin. In plants, lignin is a metabolite that hardens the wall. Plant cell wall polysaccharides are made of repeating (monosaccharides) glucose molecules.

Explanation:

The secondary cell wall is made up of layered sheaths of cellulose microfibrils, placed in parallel, providing protection, rigidity and strength to the larger plant.

Lignin works to make the secondary cell wall less flexible and less permeable to water, this makes it more resistant to degradation, and work as water containers and conductors since the lining of the the secondary cell wall would be hydrophobic.

Polysaccharides are molecules composed of long chains of monosaccharides, which are made up of glucose or fructose (sugars).
