Scientists meаsured the pressure in the xylem оf redwооd trees аt different heights аnd found that the higher they made their measurements, the lower the pressure. They extrapolated this to a pressure of zero, and concluded that the tallest a tree could grow is 122–130 meters. The tallest known tree on Earth is 112.7 meters. What assumption were the scientists making to conclude that when pressure was zero, the plant could grow no further?
