Lauren Wells Carbohydrates are biologically important to the cellular structure and function in plants and animals. Carbohydrates are classified as sugars and the polymers of different sugars. They include monosaccharides, or simple sugars; disaccharides, or double sugars; or polysaccharides, which are polymers composed of many sugar building blocks. Many components of carbohydrates that are important to the cellular structure and function are starch, cellulose and sucrose. Sucrose is important in the function of plants. It aids in the transport of carbohydrates form leaves to roots and other nonphotosynthetic organs. Starch is a major component of plants. Starch consists of glucose monomers. It enables the plant to store surplus glucose when synthesized. Plants store this starch as granules within plastids. Cellulose contributes to plants structure and function. Cellulose is a polymer of glucose and is a major component of the tough walls that enclose plant cells. Cellulose is held together by microfibrils in plant cell walls. Microfibrils are a strong building material for plants.
