In the picture
- Mature tree trunk: the larger tree that can supply sugar
- Sapling stem: the young tree that may receive extra sugar
- Fungal threads between roots: the underground pathway linking two root systems
- Golden grain in a thread: a sugar packet moving toward the sapling
Examples
- A young oak sprouting near an old oak may receive sugars from the older tree.
- A garden seedling linked to an older tree’s fungal network may grow faster.
Key takeaways
- Underground fungal threads can connect tree roots and move sugars between trees.
- Related seedlings may receive extra sugar, which can give them a growth advantage.
