Which of the following statements are correct? (A). Passive absorption occurs during day time when transpiration is in progress. (B). Passive absorption stops at night when transpiration stops. Choose the correct answer from the options given below:

Options

  1. AStatement A is correct but statement B is incorrect
  2. BBoth statement A and B are incorrecct
  3. CBoth statement A and B are correct
  4. DStatement A is incorrect but statement B is correct

Correct answer

C. Both statement A and B are correct

Step-by-step solution

Passive absorption of water is driven by the transpiration pull created by the loss of water from the aerial parts of the plant. During the day, stomata are open and transpiration is active, leading to a strong transpiration pull. Thus, passive absorption occurs during the day time when transpiration is in progress. At night, stomata generally close, transpiration stops, and the transpiration pull ceases. Consequently, passive absorption stops at night. Therefore, both statements A and B are correct. Answer: Both s
