In the picture
- A pale thread touching a root: a fungal filament meets the root.
- A blue droplet on the thread: water moves through the thread.
- A grass root mass where a thread arrives: nutrients enter the roots.
- An amber droplet on another thread: a warning signal moves toward another plant.
Examples
- In a garden, a tomato plant and a bean plant can be joined by these threads.
- In a forest, a tree and a young seedling can exchange water or nutrients through the same underground threads.
Key takeaways
- Many plant roots are connected underground by fungal threads.
- These threads can carry water, nutrients and warning signals between plants.
