Stem Tuber vs. Root Tuber: What's the Difference?

Edited by Sawaira Riaz || By Sumera Saeed || Published on January 8, 2024
Stem tubers are swollen underground stems storing nutrients, while root tubers are enlarged roots serving a similar storage function.

Key Differences

Stem tubers, like potatoes, are thickened underground stem segments storing nutrients. Root tubers, such as sweet potatoes, are modified roots that also store nutrients.

In stem tubers, buds or "eyes" can sprout into new plants. Root tubers lack these buds and reproduce differently.

Stem tubers grow from stolons or rhizomes, horizontal stems. Root tubers grow directly from the plant's root system.

The primary function of stem tubers is both storage and vegetative reproduction. Root tubers mainly serve as storage organs and are less involved in reproduction.

Stem tubers contain nodes and internodes, characteristic of stems. Root tubers, being roots, lack these stem features.
