What role does chlorophyll play in photosynthesis?

• A. It converts glucose into energy
• B. It absorbs light energy for the conversion of carbon dioxide and water
• C. It helps in respiration
• D. It transports nutrients within the plant

Answer: (B)

Chlorophyll plays a crucial role in photosynthesis by absorbing light energy, which is essential for the process itself. During photosynthesis, chlorophyll primarily captures sunlight, particularly in the blue and red wavelengths of light. This absorbed energy is then used to convert carbon dioxide and water into glucose and oxygen. The glucose produced serves as an energy source for the plant, while oxygen is released as a byproduct. The other choices do not accurately describe the role of chlorophyll. Converting glucose into energy occurs during cellular respiration, not photosynthesis, and it is separate from the function of chlorophyll. Chlorophyll is not involved in respiration, which takes place in the mitochondria of cells after glucose has been produced. Additionally, while chlorophyll is important for the overall health of the plant, it does not function in the transport of nutrients; that role is carried out primarily by xylem and phloem tissues in the plant.
