Cellulose refers to the main component present in the cell walls of plants, which assists the plants to stay strong and stiff. Humans do not possess the tendency to digest cellulose, however, it is essential in the diet as a source of fiber. Cellulose refers to a molecule that comprises hundreds and thousands of hydrogen, carbon, and atoms of oxygen.
It is an example of a natural polymer and is a long and repeating chain of a similar molecule combined together. The molecules of cellulose are held together in the form of bundles that are big enough to produce fibers. The fibers of cellulose produce long and parallel strands, which are linked together with the help of hydrogen bonds. The connected cellulose fibers are robust and offer structural support to the cell.
In an experiment, it is important that everything is exactly the same in order to achieve correct results. The only exception are the variables, the independent variable and the dependent variable.
