Cellulose

Cellulose is a complex carbohydrate found in the cell walls of plants. It is the most abundant organic compound on Earth and is a major component of plant biomass. Cellulose is made up of long chains of glucose molecules linked together, and its structure gives it strength and rigidity, providing support for plant cells and allowing them to maintain their shape.

Structure of Cellulose

Cellulose molecules are made up of linear chains of beta-glucose molecules, which are linked together by β-1,4-glycosidic bonds. The chains are held together by hydrogen bonds, forming a strong and rigid structure. This arrangement allows cellulose to form microfibrils, which provide strength to plant cell walls.

Function of Cellulose

Cellulose plays a crucial role in the structure and support of plant cells. It provides rigidity to the cell walls, allowing plants to grow upright and withstand environmental stresses. Cellulose also acts as a dietary fiber in the human diet, aiding in digestion and promoting gut health.

Chemical Properties of Cellulose

Cellulose is insoluble in water and most organic solvents due to its strong hydrogen bonding and crystalline structure. It is resistant to degradation by most enzymes and acids, which makes it a durable and long-lasting material.

Industrial and Commercial Uses

Cellulose has a wide range of industrial applications. It is used in the production of paper, textiles, and as a component in certain types of plastics. Cellulose derivatives, such as cellulose acetate and cellulose ethers, are used in the manufacture of films, fibers, and coatings.

Nature of Science

The Practice of Science - A: Scientific inquiry is a multifaceted activity; The processes of science include the formulation of scientifically investigable questions, construction of investigations into those questions, the collection of appropriate data, the evaluation of the meaning of those data, and the communication of this evaluation. B: The processes of science frequently do not correspond to the traditional portrayal of ''the scientific method.'' C: Scientific argumentation is a necessary part of scientific inquiry and plays an important role in the generation and validation of scientific knowledge. D: Scientific knowledge is based on observation and inference; it is important to recognize that these are very different things. Not only does science require creativity in its methods and processes, but also in its questions and explanations.

Define a problem based on a specific body of knowledge, for example: biology, chemistry, physics, and earth/space science, and do the following:

Use tools to gather, analyze, and interpret data (this includes the use of measurement in metric and other systems, and also the generation and interpretation of graphical representations of data, including data tables and graphs)
