Quick Answer. Plants produce oxygen as a byproduct of photosynthesis, the process that plants and other organisms use to create usable energy. Photosynthesis consists of carbon dioxide and water reacting in the presence of energy from sunlight, which produces glucose and oxygen.
Best Answer: Photosynthesis is the process by which chlorophyl in plants uses sunlight to break down carbon dioxide. The carbon is then combined with nutrients from the soil to create sugars which nourish the plant.The byproduct of this process is oxygen.Therefore photosynthesis converts carbon dioxide into oxygen. This has been a vital process for Earth's atmosphere throughout geological history.Earth's very early atmosphere had little free oxygen, so it would have been toxic to humans.herefore photosynthesis converts carbon dioxide into oxygen.
