During the process of photosynthesis, plants produce their own food. This is a crucial biochemical process for life on Earth, as it is the main way in which solar energy is captured and converted into chemical energy. Here's a step-by-step explanation of what happens:
1. Reactants: The equation begins with the reactants, which are carbon dioxide (CO₂) and water (H₂O). Specifically, six molecules of carbon dioxide and six molecules of water are needed for the reaction.
2. Sunlight: Sunlight plays a crucial role in this process. It provides the energy required for the chemical reaction to take place. This energy is typically absorbed by chlorophyll, a pigment found in the chloroplasts of plant cells.
3. Chlorophyll's Role: Chlorophyll absorbs the sunlight and uses this energy to split water molecules (H₂O) into hydrogen and oxygen. The oxygen is then released as a byproduct.
4. Formation of Glucose (C₆H₁₂O₆): The hydrogen from the split water molecules is combined with carbon dioxide (CO₂) absorbed from the air. Through a series of reactions known as the Calvin Cycle, these molecules are synthesized into glucose (C₆H₁₂O₆), a simple sugar that serves as an energy source for the plant.
5. Products: The overall products of photosynthesis are one molecule of glucose (C₆H₁₂O₆) and six molecules of oxygen (O₂). The oxygen is released into the atmosphere, which is essential for the survival of aerobic organisms, including humans.
To summarize, photosynthesis is a process by which plants convert carbon dioxide and water into glucose and oxygen using the energy from sunlight. This not only provides food and energy for the plants themselves but also produces the oxygen that almost all other life forms need to survive.
The summarized equation for the process is:

Sunlight is the key energy source driving this reaction, absorbed by chlorophyll in the plant cells.
