Given below are two statements:Statement I: The forces generated by transpiration can lift a xylem-sized column of water over height.Statement II: Transpiration cools leaf surfaces sometimes to degrees, by evaporating cooling.In the light of the above statements, choose the most appropriate answer from the options given below:

  1. A
    Both Statement I and Statement II are correct
  2. B
    Both Statement I and Statement II are incorrect
  3. C
    Statement I is correct but Statement II is incorrect
  4. D
    Statement I is incorrect but Statement II is correct

Solution & Step-by-step Explanation

Statement I is correct: Measurements show that the transpiration pull-driven transport of water can create enough force to lift a column of water over high.Statement II is correct: One of the primary functions of transpiration is to cool the leaves, preventing heat damage. It can lower the temperature of the leaf surface by through evaporative cooling.
