What is the primary source of energy for photosynthesis?

• A. Water
• B. Sunlight
• C. Glucose
• D. Carbon Dioxide

Answer: (B)

The primary source of energy for photosynthesis is sunlight. During this process, plants, algae, and certain bacteria capture sunlight using pigments like chlorophyll. This light energy is then used to convert carbon dioxide and water into glucose and oxygen. The captured energy initiates a series of biochemical reactions that ultimately store energy in the form of glucose, which can later be used by the plant for growth and development or can be consumed by other organisms. Sunlight's role as the driving force behind the entire process is fundamental, as it provides the energy necessary to synthesize organic compounds from inorganic materials.
