    Question

    The rate of transpiration accelerates due to

    A increase in temperature Correct Answer Incorrect Answer
    B decrease in temperature Correct Answer Incorrect Answer
    C no change in temperature Correct Answer Incorrect Answer
    D low humidity Correct Answer Incorrect Answer

    Solution

    Higher temperatures increase the rate of transpiration by enhancing water evaporation from leaf surfaces. Information Booster:         

    1. Other factors affecting transpiration include light, wind, and humidity.
    2. High humidity reduces the transpiration rate.
    3. Wind enhances transpiration by removing water vapour.
