Storage Organs

A storage organ is a part of a plant specifically modified to store energy (e.g. carbohydrates) or water

  • They are usually found underground (for protection from herbivores) and result from changes to roots, leaves or stems

Examples of storage organs include:

  • Bulbs – Modified leaf bases (found as underground vertical shoots) that contain layers called scales (e.g. onions)
  • Storage Roots – Modified roots that store water or food in an enlarged central stele (e.g. carrots)
  • Tubers – Horizontal underground stems that store carbohydrates (e.g. potatoes)
