Today, we'll talk about photosynthesis. Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy into chemical energy stored in glucose molecules. This process occurs in chloroplasts, where chlorophyll captures sunlight and initiates a series of reactions that produce glucose and oxygen as byproducts. Glucose serves as a primary source of energy for the organism, while oxygen is released into the atmosphere, supporting life for many organisms, including humans. Photosynthesis is crucial for maintaining the balance of oxygen and carbon dioxide in the atmosphere, making it essential for life on Earth.
