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.
All plants produce oxygen during the process of photosynthesis, which is how plants make food, or energy. How much oxygen is produced can vary widely from species to species. In most plants, the production of oxygen occurs during the day. Some plants, however, produce oxygen at night.
