Cellulose is a polysaccharide and the most abundant organic compound on the Earth's surface.
It is an important organic molecule due to its strong structure which provides a wide variety of functions.
Cellulose is a major component of tough cell walls that surround plant cells and is what makes plant stems, leaves, and branches very strong.
The molecules of cellulose are arranged such that they are parallel to each other joined by hydrogen bond. this arrangement forms long structures that combine with other cellulose molecules producing a strong support structure.
