Prepare and present a short note on the role of plants in maintaining the oxygen level. |

Answer» In the presence of sunlight, the chlorophyll present in plants forms glucose by combining CO2 and water. As a result of this reaction (photosynthesis), oxygen is liberated. This helps to maintain the oxygen level in the atmosphere. 6CO2 + 6H2O → C6H12O6 + 6O2 |
