🧠 Remember it

Photosynthesis

The recipe: sunlight + water + carbon dioxide → glucose + oxygen, cooked inside the green chlorophyll. "A leaf drinks CO₂ and water, and with sunlight cooks sugar, breathing out oxygen."

🌏 In real life

A peepal or banyan tree cooling a village square is a giant food-and-oxygen factory: every leaf is quietly turning sunlight into the sugar that feeds the tree and the oxygen you breathe.

📝 Quick notes

  • Equation: 6CO₂ + 6H₂O --(sunlight, chlorophyll)--> C₆H₁₂O₆ + 6O₂.
  • It happens in the chloroplasts, which contain the green pigment chlorophyll.
  • Raw materials: carbon dioxide (from air through stomata) and water (from soil through roots).
  • Products: glucose (stored as food/energy) and oxygen (released into the air).

🎯 Test yourself

Where in the cell does photosynthesis take place?

In the chloroplasts, which contain chlorophyll.
