What is the primary factors need in photosy nthesis?

The primary factors needed for photosynthesis are sunlight, carbon dioxide, and water. Sunlight provides the energy required for the process, while carbon dioxide is absorbed from the atmosphere and water is taken up from the soil. These components are essential for plants to convert light energy into chemical energy, producing glucose and oxygen as byproducts. Additionally, chlorophyll, the green pigment in plants, plays a crucial role in capturing light energy during this process.
