Storage organ
Et lagerorgan er en del af en plante, der er specielt modificeret til lagring af energi (generelt i form af kulhydrater) eller vand. Lagerorganer vokser ofte under jorden, hvor de er bedre beskyttet mod angreb fra planteædere. Planter, der har et underjordisk lagerorgan, kaldes geofytter i Raunkiærs klassifikationssystem for planteformer. Opbevaringsorganer fungerer ofte, men ikke altid, som flerårige organer, der gør det muligt for planter at overleve ugunstige forhold (f.eks. kulde, overdreven varme, mangel på lys eller tørke).
A storage organ is a part of a plant specifically modified for storage of energy (generally in the form of carbohydrates) or water. Storage organs often grow underground, where they are better protected from attack by herbivores. Plants that have an underground storage organ are called geophytes in the Raunkiær plant life-form classification system. Storage organs often, but not always, act as perennating organs which enable plants to survive adverse conditions (such as cold, excessive heat, lack of light or drought).
