Root Tubers. A root tuber, also called a storage root, is a modified root that doubles as a nutrient storage for the plant. A root tuber is similar in function and appearance to a stem tuber, but it can grow from any underground point on the plant. Root tubers produce no leaves and do not die as winter approaches. Rather, they live and store valuable nutrients while the plant is dormant.
