Rocks provide a timeline. for Earth. Layers of sedimentary rocks. show relative age. Fossils are clues in the story of Earthâs past. But for the story to make. sense, the clues need to be arranged in order. is the age. of an event or object in relation to other events or objects. You probably. know relative ages for many things in your life.
Cellulose is an organic compound with the formula (C 6H 10O 5) n, a polysaccharide consisting of a linear chain of several hundred to many thousands of Î²(1â4) linked D-glucose units.Cellulose is an important structural component of the primary cell wall of green plants, many forms of algae and the oomycetes.Some species of bacteria secrete it to form biofilms. Cellulose is the most abundant organic polymer on Earth.The cellulose content of cotton fiber is 90%, that of wood is 40â50% and that of dried hemp is approximately 45%. Cellulose is mainly used to produce paperboard and paper.ellulose is an important structural component of the primary cell wall of green plants, many forms of algae and the oomycetes.

Starch and Cellulose belong to the same group of carbohydrates. Carbohydrates are one of the common forms of energy sources in food. They have the molecular formula CH2O. They are macromolecules made up of several monomer units of glucose.lthough starch and cellulose are both polymeric forms of glucose, they differ in the properties. These differences tend to be the result of the difference of a single chemical bond between the monomeric units. The varied nature makes the carbohydrates to play both energy providing function as well as structural roles.
