Caption: Many plants store starch and other sugars in their roots. Organs swollen with nutritive reserves are called tubers. Many vegetables, such as salsify, carrots, and sugar beets, are root tubers. Certain plants in dry zones have roots full of water reserves so that they can survive during long periods of drought.
