Given below are two statements :

Statement I : The forces generated by transpiration can lift a xylem-sized column of water over 130 meters height.

Statement II : Transpiration cools leaf surfaces sometimes 10 to 15 degrees, by evaporative cooling.

In the light of the above statements, choose the most appropriate answer from the options given below :

1. Statement I is incorrect but Statement II is correct.

2. Both Statement I and Statement II are correct.

3. Both Statement I and Statement II are incorrect.

Best answer

Answer: 2. Both Statement I and Statement II are correct.

Key idea: Both statements are standard facts about transpiration.

  • Statement I is correct: the pull of transpiration is strong enough to lift water in xylem over 130 m, taller than the tallest trees.
  • Statement II is correct: evaporation cools leaf surfaces, sometimes by 10 to 15 degrees.

Option 2.
