The xylem water tension is strong enough to pull water to:
Correct answer: A. 200 meters
- A. 200 meters
- B. 400 feet
- C. 300 meters
- D. 500 feet
Explanation
The correct answer is "200 meters." Xylem water tension, a result of transpiration and the cohesive and adhesive properties of water, can pull water to great heights in plants, up to around 200 meters. This limit is determined by the physical properties of water and the structure of the xylem. The other options represent heights that are either within a typical range but not the maximum (400 feet, 500 feet) or exceed the maximum observed in nature (300 meters).
