Correct option is A
During photosynthesis, plants use sunlight, water, and carbon dioxide to produce glucose and oxygen. The chemical equation for photosynthesis is:
6CO2+6H2O→sunlight, chlorophyllC6H12O6+6O26CO_2 + 6H_2O \xrightarrow{\text{sunlight, chlorophyll}} C_6H_{12}O_6 + 6O_26CO2+6H2Osunlight, chlorophyllC6H12O6+6O2
In this process, oxygen is generated as a by-product when water molecules are split during the light-dependent reactions. The released oxygen is then expelled into the atmosphere.
Information Booster
- Photosynthesis occurs in the chloroplasts of plant cells.
- The light-dependent reaction takes place in the thylakoid membranes, producing oxygen as a waste product.
- This oxygen is vital for the survival of most organisms as it is used in cellular respiration.
