उत्तर
Photosynthesis is defined as the process in which chlorophyll-containing plant cells synthesize food in the form of carbohydrates using carbon dioxide and water in the presence of solar energy.

Photosynthesis
Sources of raw materials required for photosynthesis:
- Photosynthesis is the process by which green plants synthesize food, and it occurs mostly in their leaves.
- The leaves contain a green pigment known as chlorophyll. It aids plants in absorbing the energy of sunlight.
- This energy is needed to produce food from carbon dioxide and water. Chlorophyll, sunlight, carbon dioxide, and water all contribute to the photosynthetic process.
- The leaves absorb solar energy, which is stored in the plant as chemical energy.
Thus, photosynthesis can be represented by the following equation.
\[\ce{\underset{(Carbon dioxide)}{6CO2} + \underset{(Water)}{6H2O} ->[Sunlight][Chlorophyll] \underset{(Carbohydrates)}{C6H12O6} + \underset{(Oxygen)}{6O2}}\]
