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.
Interestingly enough, when plants âburnâ the glucose produced by photosynthesis it results in a chemical process that is the opposite of photosynthesis. This process, where sugars react with oxygen to produce water and carbon dioxide, is called respiration.
