The ginger roots shown above are an example of rhizomes. Rhizomes are the modified stem of a plant that are found underground. These stems release roots and nodes in order for the plant to grow deeper and gain more nutrients. The rhizome is also used a storage for proteins, starches, and other nutrients. If a piece of the rhizome has been cut and planted elsewhere, it can give rise to a whole new plant of the rhizome’s origin.
