What process uses chlorophyll to convert carbon dioxide into sugar?

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

Answer: (A)

Photosynthesis is the process in which plants use chlorophyll, the green pigment found in their leaves, to capture sunlight and convert carbon dioxide and water into glucose (sugar) and oxygen. This biochemical reaction is essential for plant growth and energy production. During photosynthesis, light energy is transformed into chemical energy stored in the form of sugars, which serve as food for the plant and other organisms that consume plants. This process is fundamental to life on Earth, as it not only provides energy for plants but also produces oxygen, which is vital for many living organisms. Other processes listed, such as respiration, transpiration, and fermentation, serve different functions in biological systems and do not involve the conversion of carbon dioxide into sugar through chlorophyll and photosynthesis.
