Photosynthesis is the process by which plants, algae, and some bacteria convert sunlight into energy, sustaining life on Earth. It involves light-dependent reactions and the Calvin cycle, producing oxygen and glucose. Innovations in artificial photosynthesis and quantum biology are exploring efficient energy conversion, with implications for renewable energy and agriculture. Understanding photosynthesis is key for ecological balance and optimizing crop yields.
