About Lesson
TUBER
- A tuber is a fleshy storage organ formed from either a stem or root
- A potato tuber is formed at the end of the underground stem, and can produce new shoots from eyes or buds on its surface
- Other plants form tubers on their roots, which do not produce shoots but are used only for storing food
- During the growing season, the plant uses the food stored in the fleshy tuber, and new tubers are formed at the ends of the current season’s underground stems
- Root tubers which are used solely as food storage organs are more or less permanent structures, and constantly replenish their reserves
