Trees are among the most extreme and successful lifeforms on Earth – they build their bodies from thin air (CO₂), pump water at pressures that’d crush a human, and grow using a living cable system (xylem and phloem) wrapped in layers of dead cells. Under their bark sits a razor-thin cambium of living cells that tirelessly moves water hundreds of meters, lays down indestructible wood, and keeps millions of processes in sync.
This Kurzgesagt video dives into the nuts and bolts of tree biology: how they’re made, what makes them so resilient (even flirting with immortality), and why these ancient giants rule the terrestrial world.
