How Photosynthesis Works – Step by Step

How Photosynthesis Works – Step by Step

The map in words

  • Sunlight hits the Leaf
    • Chlorophyll absorbs Sunlight
      • Energy splits Water molecule
        • Oxygen released through Stomata
        • Hydrogen ions formed
          • H ions combine with Carbon dioxide
            • Glucose is formed
              • What happens to Glucose?
                • Used immediately: Energy for cell activities
                • Stored: Converted to Starch in leaf
                  • At night: Starch to Sucrose
                    • Transported via Phloem to all plant parts
