Sweet potato, scientifically known as Ipomoea batatas, is the world’s seventh most important food crop, after wheat, rice, maize, potato, barley and cassava. It is a tuberous root, which is a modified lateral root, enlarged to function as a storage organ; thus it has high nutritional value.
The sweet potato has yellow or orange flesh, and its thin skin may either be white, yellow, orange, red or purple. Sometimes this root vegetable will be shaped like a potato, being short and blocky with rounded ends, while other times it will be longer with tapered ends. Its plant is a creeper with heart shaped or lobed leaves.
