It is called photosynthesis—the astonishing cellular ballet that captures sunlight and converts it into chemical energy, literally turning light into life. Plants perform this miracle every second of every day, not only to survive, but to sustain nearly all life on Earth. Photosynthesis is the process by which green plants and certain other organisms transform light energy into chemical energy. During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds. Photosynthesis changes sunlight into chemical energy, splits water to liberate O 2, and fixes CO 2 into sugar. Most photosynthetic organisms are photoautotrophs, which means that they are able to synthesize food directly from carbon dioxide and water using energy from light. Learn about photosynthesis with a definition, diagram, and glossary. Discover the chemical reaction formula and explore the process. Photosynthesis not only changed the air but also laid the foundation for the evolution of all plants and animals. By enabling the storage of solar energy in chemical form, it provided a new, rich energy source—glucose—that could be passed through food chains.

Photosynthesis is the process by which plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar. Explore the photosynthesis process with detailed steps, chemical equation, and diagrams. Understand how plants convert light into energy. It is the process by which green plants, algae, and certain bacteria convert light energy from the sun into chemical energy that is used to make glucose. The word ‘photosynthesis’ is derived from the Greek word phōs, meaning ‘light’ and synthesis meaning ‘combining together.’.
