Photosynthesis Formula Equation with Lots of Key Facts

Rate this post

Photosynthesis, the process by which plants, algae, and some bacteria turn sunlight, water, and carbon dioxide into food and oxygen, is the basis of all life on Earth. It’s like a magical alchemy show happening right before our eyes, fueled by the power of the sun. Let’s delve into the formula and key facts of this essential process:

Photosynthesis Formula

The balanced chemical equation for photosynthesis is:

6CO₂ + 6H₂O + Light Energy → C₆H₁₂O₆ + 6O₂

Breaking the Formula


  • 6CO₂: Six molecules of carbon dioxide, are absorbed from the air through tiny openings called stomata on leaves.
  • 6H₂O: Six molecules of water, taken up by the plant’s roots and transported to the leaves.
  • Light Energy: Captured by chlorophyll, a green pigment found in chloroplasts within plant cells.


  • C₆H₁₂O₆: One molecule of glucose, a simple sugar used for immediate energy or stored for later. This is the “food” created by photosynthesis.
  • 6O₂: Six molecules of oxygen, released into the atmosphere for us to breathe!

Key Facts

  • Chlorophyll, the Green Magician: This pigment acts like a solar panel, absorbing sunlight and channeling its energy to power the process.
  • Water Splitting: Using the captured energy, plants break down water molecules into oxygen and hydrogen ions.
  • Carbon Dioxide Fixation: Hydrogen ions then combine with carbon dioxide to form glucose, the plant’s fuel.
  • The Oxygen We Breathe: As a byproduct of photosynthesis, plants release oxygen into the atmosphere, replenishing the air we need to survive.
  • More Than Just Food: Photosynthesis also plays a crucial role in regulating the Earth’s climate by removing carbon dioxide, a greenhouse gas, from the atmosphere.
  • Renewable Energy Source: Scientists are exploring ways to use artificial photosynthesis to create clean energy from sunlight and water, potentially revolutionizing our energy future.

Most Important Points for Competitive Exam

  • Source of Oxygen: The oxygen produced during photosynthesis comes from water, not carbon dioxide.
  • Source of Oxygen in Glucose: The oxygen in glucose comes from carbon dioxide, not water.
  • No. of reactants Molucule: 6 molecules of carbon dioxide (6CO₂) and 6 molecules of water (6H₂O) are required to produce 1 molecule of glucose (C₆H₁₂O₆).
  • Glucose Formation: Glucose is synthesized from the carbon dioxide taken in during photosynthesis.
  • Requirement of Energy: Light energy is absorbed during this process.

Fun Fact For You

  • A single mature tree can produce enough oxygen for two people in a year!

Remember, photosynthesis is not just a chemical equation; it’s a vital process that connects plants, animals, and the entire planet in a delicate balance. Let’s appreciate this magical alchemy of life and strive to protect the green guardians that make it all possible!
