HUMAN NUTRITION

Detailed explanation-1: -In the cell walls of higher plants, the tensile fibers are made from the polysaccharide cellulose, the most abundant organic macromolecule on Earth, tightly linked into a network by cross-linking glycans.

Detailed explanation-2: -Structural components meant for the plant’s rigidity and form include cellulose (polymerized glucose), hemicellulose (polymerized xylose, or wood sugar), lignin (polymerized n-propyl benzene), and calcium pectate.

Detailed explanation-3: -The most important structural component of plant cell walls is cellulose. Cellulose is a carbohydrate found in the cell wall of plants. The carbohydrate is a polysaccharide structure. Polysaccharide is made up of a long chain of several sugar units bonded together by chemical linkage.

Detailed explanation-4: -An example of structural support is the deposition of cellulose in plant cell walls, making cells stronger and helping them keep their shape. Lignin is another example, which is deposited in the walls of xylem vessels, making them waterproof and rigid.
