What is Photosynthesis?
Photosynthesis is the process by which green plants, algae, and some bacteria make their own food using sunlight, carbon dioxide from the air, and water from the soil.

Where Does It Happen?
Photosynthesis mainly takes place in the leaves of the plant, inside tiny cell parts called chloroplasts, which contain the green pigment chlorophyll.

The Chemical Reaction
The basic formula is:
6CO₂ + 6H₂O + light energy → C₆H₁₂O₆ + 6O₂.
It means carbon dioxide and water, with sunlight, turn into glucose (sugar) and oxygen.

Steps of Photosynthesis
1. Chlorophyll absorbs sunlight.
2. Water is split into hydrogen and oxygen.
3. Oxygen is released.
4. Carbon dioxide is used to make glucose.
5. The plant uses glucose for energy and growth.

Why Is It Important?
Photosynthesis produces oxygen, provides food, reduces carbon dioxide, and supports all life by being the base of the food chain.
