In a classic (or early) experiment to determine how large the forces are that allow leaves to pull water from the soil, the rate at which water flowed from a reservoir into the cut tip of an actively transpiring plant was _____ the flow rate through the branch tip when it was subsequently attached to a vacuum pump.

Question

Quizplus · Accepted Answer

In classic experiments, it was observed that the rate at which water flowed from a reservoir into the cut tip of an actively transpiring plant was greater than the flow rate through the branch tip when it was subsequently attached to a vacuum pump. This demonstrates the remarkable efficiency of the plant's transpiration pull, which can exceed the force generated by a man-made vacuum pump.
