    Question

    Which of the following helps in thermoregulation in plants?

    A.

    photosynthesis

    B.

    Root stress

    C.

    Evaporation

    D.

    Exploitation

    Correct option is C

    The correct answer is: (c) Evaporation

    • Evaporation, specifically through the process of transpiration, plays a key role in thermoregulation in plants.
    • Transpiration involves the loss of water vapor from the stomata of leaves. This process helps cool the plant, much like sweating cools the human body. By regulating water loss, plants can maintain their internal temperature and prevent overheating under hot conditions.

    Information Booster:

    • Photosynthesis: Converts sunlight into energy; indirectly linked to thermoregulation via stomatal activity.
    • Root stress: Reduces water uptake and affects transpiration; not a thermoregulation mechanism.
    • Evaporation (Correct Answer): Transpiration cools the plant by releasing water vapor, aiding thermoregulation.
    • Exploitation: Unrelated to plant thermoregulation.
