Photosynthesis is the biological process by which plants, algae, and certain bacteria convert light energy into chemical energy to fuel their growth.
It occurs in chloroplasts, where pigments like chlorophyll absorb sunlight. During photosynthesis, carbon dioxide from the air and water from the soil are combined to produce glucose and oxygen.
This energy-conversion process is fundamental for sustaining life on Earth, as it generates the oxygen we breathe and provides the foundation of the food chain, as plants serve as primary producers.
