Pando, a grove of aspens in Utah, is a single organism with about 47,000 trunks joined by the same root system.
Why it is true
All the trunks are genetically identical clones that sprouted from one root system. Together they cover about 43 hectares and weigh around 6,000 tonnes, making Pando one of the heaviest organisms on Earth.
