what is pectnin and lignin?
Asked by kaushal_012 | 10 Aug, 2014, 06:48: AM
Expert Answer
Lignin is a constituent of the cell walls of almost all dry land plant cell walls. It prevents the absorption of water by these polysaccharides in plant cell walls and allows the efficient transport of water in the vascular tissues.
Pectin is a complex carbohydrate, which is found both in the cell walls of plants, and between the cell walls, helping to regulate the flow of water in between cells and keeping them rigid.
