NEET · BiologyEasy
Which process is primarily responsible for the upward movement of water in tall trees?
- A.Active transport
- B.Transpiration pull
- C.Root pressure
- D.Imbibition
Show correct answer & step-by-step solution
Correct answer: B — Transpiration pull
Solution
- Water evaporates from the leaf surface through stomata.
- This creates a negative pressure potential in the xylem.
- This tension pulls the water column upward.
- Hence the answer is (B).
