A storage organ is a part of a plant specifically modified for storage of energy (generally in the form of carbohydrates) or water. [1] Storage organs often grow underground, where they are better protected from attack by herbivores .
In botany, a bulb is a short underground stem with fleshy leaves or leaf bases [1] that function as food storage organs during dormancy. In gardening, plants with other kinds of storage organ are also called ornamental bulbous plants or just bulbs.
The pseudobulbs are relatively short lived (1–5 years), but are continually produced from the growing tip of the rhizome and may persist for years after its last leaves senesce. The term pseudobulb is used to distinguish the above-ground storage organ from other storage organs derived from stems that were underground, namely corms or true ...
A root tuber, tuberous root or storage root is a modified lateral root, enlarged to function as a storage organ. The enlarged area of the tuber can be produced at the end or middle of a root or involve the entire root. It is thus different in origin, but similar in function and appearance, to a stem tuber.

The bulb's storage organs contain moisture and nutrients that are used to survive these adverse conditions in a dormant state. When conditions become favourable the reserves sustain a new growth cycle. In addition, bulbs permit vegetative or asexual multiplication in these species. [1] [2] Ornamental bulbs are used in parks and gardens and as ...

A stem tuber is a thickened part of a rhizome or stolon that has been enlarged for use as a storage organ. [10] In general, a tuber is high in starch, e.g. the potato, which is a modified stolon. The term "tuber" is often used imprecisely and is sometimes applied to plants with rhizomes.
