What does photosynthesis's form in a leaf of plant first?

Photosynthesis in a leaf begins in the chloroplasts, where chlorophyll captures sunlight. This energy is then used to convert carbon dioxide from the air and water from the soil into glucose and oxygen. The process can be summarized by the equation: 6CO₂ + 6H₂O + light energy → C₆H₁₂O₆ + 6O₂. Overall, photosynthesis provides essential energy for the plant and contributes oxygen to the atmosphere.
