The chemical composition of a substance does not change. |
The chemical composition of a substance changes. |

Most changes are reversible |
Most changes are irreversible. |

No new substances are formed. For example, Ice → Water → Steam |
New substances are formed. For example, Paper → Ashes |
Photosynthesis is the process by which chlorophyll-containing cells synthesize food in the form of carbohydrates from carbon dioxide and water using sunlight.
Therefore, the raw materials required for photosynthesis are CO2 and H2O, and the products formed are carbohydrates and O2.
Photosynthesis is a chemical change because a new substance (like glucose) is formed in that process.6CO2 + 6H2O → C6H12O6 + 6O2
