accessdate=2007-05-06] Other underground plants are often, erroneously, called root vegetables. Root vegetables include both trueroot s such astuberous root s andtaproot s, but exclude non-roots such astuber s,rhizome s,corm s, andbulb s. Several types contain both taproot andhypocotyl tissue, and it may be difficult to distinguish the two.Regardless of anatomical type, root vegetables are generally
storage organ s, enlarged to store energy in the form ofcarbohydrate s. They differ in the concentration and the balance betweensugar s,starch es, and other types of carbohydrate.Of particular economic importance are those with a high carbohydrate concentration in the form of starch. These starchy root vegetables are important
staple food s, particularly in tropical regions. They overshadow thecereal s throughout much ofWest Africa ,Central Africa , andOceania , where they are used directly or mashed to makefoufou or poi.List of underground vegetables by anatomical type
