Citrus sinensis, better known as the common sweet orange and  is a member of the citrus family, which groups it into the same category as limes, grapefruits, and many others.  The name of this fruit originates from “golden apple,” which is what it used to be called.  This fruit is an extremely important crop in the United States and across the world.  It is used in many commercial applications because of its sour flavor, sweet aroma, and abundant source of Vitamin C. People are not the only organism that eat oranges, many other organisms such as bacteria and fungi rely on the orange as a food source as well.  These interactions with other organisms and the personal adaptions of Citrus sinensis make it a very interesting organism to study and learn about.
