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.

They release carbon dioxide and take in oxygen from the air around them. Plants, unlike other living things, can produce their own oxygen in a process called photosynthesis. Photosynthesis is the opposite of respiration. In photosynthesis, plants' carbon dioxide is absorbed by the plant and from that, oxygen is produced.Plants respire all the time, day or night. However, they only photosynthesize during the day, when the sun is out. Every part of a plant breathes.
