Root vegetables

Root vegetables are underground plant parts eaten by humans or animals as food. In agricultural and culinary terminology, the term applies to true roots such as taproots and tuberous roots as well as non-roots such as bulbs, corms, rhizomes, and stem tubers. Root vegetables are generally storage organs, enlarged to store energy in the form of carbohydrates. They differ in the concentration and balance of starches, sugars, and other carbohydrates.
