Short notes on Significance of Photosynthesis:
Photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize food from carbon dioxide and water. Green plants absorb carbon dioxide from air and water from the soil. In the presence of sunlight and chlorophyll, they synthesize starch as food. They release oxygen as a by-product.
CO2 + H2O --------> C6H12O6 + O2
Carbon dioxide + Water --------------> Glucose + Oxygen
Hence, photosynthesis provides food for most of the living organisms present on earth. Photosynthesis releases oxygen into the environment which is utilised by animals, human beings and many microbes in the process of respiration.
