उत्तर
- The factor studied in this experiment is Sunlight.
- It will be observed that only the parts of the leaf that could get sunlight turn blue-black, and the parts covered with black paper do not turn blue, as they could not synthesise starch.
- Photosynthesis is the process by which living plant cells, containing chlorophyll, produce food substances (glucose and starch) from carbon dioxide and water, using light energy. Plants release oxygen as a by-product during photosynthesis.
- \[\ce{6CO2 + 12H2O ->[Light energy][Chlorophyll] C6H12O6 + 6H2O + 6O2\uparrow}\]
