Question
Chapter 26, Problem 5LTB
To write:
The process happens when the column of xylem is under extreme tension inside a plant.
Summary Introduction
Introduction:
Tension is the force that allows water column to pull into a syringe when the plunger is dragged up. In plants, tension causes water molecules from the xylem to be extracted out into the leaf to replace the evaporated water.
