Here's why:
* Photosynthesis is the process by which plants, algae, and some bacteria use sunlight, water, and carbon dioxide to produce glucose (sugar) and oxygen.
* The light energy is captured by chlorophyll within chloroplasts and used to convert these inorganic molecules into organic molecules, storing the energy in chemical bonds.
While other processes like cellular respiration and ATP production are important for energy use, they are not directly driven by light energy. They rely on the energy stored in the chemical bonds of glucose produced through photosynthesis.
