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.
