During photosynthesis, plants take in carbon dioxide and release oxygen.
- Plants take in carbon dioxide (CO2) and water (H2O) from the air and soil during photosynthesis.
- The plant then releases the oxygen into the atmosphere while storing energy in the glucose molecules.
- Plants respire throughout the day, while photosynthesis takes place only in the presence of sunlight.
- In the daytime, CO2 produced during respiration is used by plants in photosynthesis. So, CO2 is not released into the environment.
- The oxygen produced during photosynthesis is released into the air via stomata.
- There is no oxygen released at night since there is no photosynthesis.
