The structure of a cellulose molecule relate to the molecule's function by fitting together very well and they become rigid like a cell wall. This helps since they mainly function as structural support for cells. Hope this answers the question.
The definition of cellulose is that is is substance that makes the fibers and cell walls of plant. Cellulose is most abundant organic polysaccharide molecules in earth.
Function:
The plant cell are surrounded by cell wall. The main component of cell walls is cellulose. The cellulose make stems, leaves and branches. So it play an important role in building of tissues. So it give the shape to plant.
The molecules of cellulose have hydroxyl group that form hydrogen bonding with other cellulose and prrovide support to plant. So n plant it is strong supporting material.
