Detailed explanation-1: -Potatoes are stem tubers – enlarged stolons thicken to develop into storage organs. The tuber has all the parts of a normal stem, including nodes and internodes. The nodes are the eyes and each has a leaf scar.
Detailed explanation-2: -Potatoes and yams are tubers, whereas taro and cocoyams are derived from corms, underground stems, and swollen hypocotyls. Cassava and sweet potatoes are storage roots and canna and arrowroots are edible rhizomes.
Detailed explanation-3: -Tubers are usually high in starch. Examples are kūmara, potatoes, (storage root), yam, taro, Jerusalem artichoke and ulluco.
Detailed explanation-4: -The edible part of the potato is the underground “tuber” which is an enlarged underground storage portion of the potato plant. The tuber develops from underground stems called stolons once the plants are 6 to 8 inches tall, or around 5 to 7 weeks after planting.
