Trees Are So Weird

Kurzgesagt dives into the astonishing biology of trees—how they literally build their bodies from thin air (aka CO₂), pump water hundreds of meters sky-high under pressures that would crush us, and keep growing with a living cambium layer nestled between bark and wood.

By wrapping “living cables” of xylem in layers of dead cells, trees create indestructible support and water-conduction systems that let them tower tall, live for centuries (or millennia), and shrug off damage—making them some of the most extreme, resilient, and seemingly immortal organisms on Earth.
