Underground Root Threads
Open to everyone until Friday, October 2
To keep it, print it while it is open.
Below the soil, pale threads join the roots of different plants. Water, nutrients and warning signals can travel along these threads from one plant to another.
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.
