À propos de cet audio

Explore the incredible physics of sap ascent, where dead xylem cells function as microscopic straws to pull water hundreds of feet into the air using negative pressure and transpiration. Discover how giants like the Coast Redwood overcome hydraulic resistance through conduit widening, avoid the blockages of cavitation, and even "drink" coastal fog directly through their leaves to thrive at the very limits of biological height.
