Solution
Photosynthesis:
Photosynthesis is the process of conversion of light energy (sunlight) into chemical energy (food) by using carbon dioxide, water and chlorophyll as raw materials.
Oxygen is evolved as a by-product of the process.
6 CO2 + 12 H2O → Glucose (C6H12O6) + 6 H2O + 6 O2
It takes place in the chloroplast of the leaves.
Chloroplast contains green color chlorophyll pigment essential for absorbing sunlight.
