What is the symbol equation for photosynthesis?

The symbol equation for photosynthesis is represented as 6CO2 + 6H2O → C6H12O6 + 6O2. This equation encapsulates the essential process by which green plants, algae, and some bacteria convert carbon dioxide and water into glucose and oxygen, using sunlight as the energy source.

In this equation, six molecules of carbon dioxide (6CO2) and six molecules of water (6H2O) react to form one molecule of glucose (C6H12O6) and six molecules of oxygen (6O2). The presence of both glucose and oxygen as products indicates that the process not only produces energy-rich organic compounds (glucose) but also releases oxygen, which is vital for aerobic life on Earth.

The correct representation includes both oxygen and glucose, highlighting the significance of photosynthesis in contributing to the atmospheric oxygen levels and providing energy for various life forms. Other choices either leave out essential products or reactants or misrepresent the substances involved, which would not accurately describe the complete process of photosynthesis.
