Plants do not have any specialised organs like lungs to breathe; hence, they respire through stomata, which help in gaseous exchange. Which of the following is the correct chemical reaction for respiration in plants?

Answer: D. Sugar + Oxygen → Carbon dioxide + Water + Energy

During respiration, plants (like all living organisms) break down sugar (glucose) using oxygen to release the energy needed for growth and survival. This process produces carbon dioxide and water as byproducts.
