Stem storage and perennating organ

Explanation:
Perennating organs are structures that store energy and allow a plant to survive unfavorable seasons, then regrow. A tuber fits this role perfectly because it is an underground swollen stem that stores starch and bears buds (eyes) that can sprout into new shoots. This combination of energy storage in stem tissue and the ability to produce new plants makes it the classic stem-based perennating organ; potato is the familiar example. Bulbs store mainly in fleshy leaves around a short stem, while rhizomes are horizontal stems that spread and also store resources, and roots store nutrients but are not stems.
