    Question

    Which of the following are the end products of respiration in plants?

    A.

    CO₂ and O₂

    B.

    Glucose and O₂

    C.

    O₂ and Energy

    D.

    CO₂, H₂O and Energy

    Correct option is D

    The correct answer is (d) CO₂, H₂O and Energy.
    Explanation:
    • Respiration in plants is a process where glucose (C₆H₁₂O₆) is broken down with the help of oxygen (O₂) to produce carbon dioxide (CO₂), water (H₂O), and energy (in the form of ATP).
    • The general equation for respiration is:

    C₆H₁₂O₆ (Glucose)+6O₂ (Oxygen)→6CO₂ (Carbon dioxide)+6H₂O (Water)+Energy (ATP)

    • In this process:
      • CO₂ is released as a by-product.
      • H₂O is formed as a result of metabolic reactions.
      • Energy is generated, which is used by the plant for various activities.

    Thus, the end products of respiration in plants are CO₂, H₂O, and Energy, making D the correct option.
