2. Tuber Definition
A much thickened underground part of a stem or rhizome, e.g., in the potato, serving as a food reserve and bearing buds from which new plants arise. (Oxford Dictionary)
Tubers are various types of modified plant structures that are enlarged to store nutrients. They are used by plants to survive the winter or dry months, to provide energy and nutrients for regrowth during the next growing season, and as a means of asexual reproduction.[1] There are both stem and root tubers. (Wikipedia)

Many are edible
Reproduces asexually (new tuber can be derived from the parent tuber)

(Oxford Dictionary)
Plant propagation is the process of creating new plants from a variety of sources: seeds, cuttings, bulbs and other plant parts. Plant propagation can also refer to the artificial or natural dispersal of plants. (Wikipedia)
