What is the process by which a plant converts sugar into CO2, water and energy?

• A. Transpiration
• B. Germination
• C. Respiration
• D. Photosynthesis

Answer: (C)

Cellular respiration in plants converts sugar into energy. In this process, glucose is broken down in the mitochondria using oxygen, releasing chemical energy stored as ATP. Carbon dioxide and water are produced as waste products. This energy powers the plant’s cellular activities, growth, and maintenance. Photosynthesis, by contrast, uses light to build sugars from carbon dioxide and water and releases oxygen. Transpiration is the loss of water from the plant, not energy production, and germination is the seed’s sprouting process. Therefore, the transformation of sugar into CO2, water, and usable energy is the hallmark of respiration.
