Oxygen in plants primarily comes from the process of photosynthesis, where it is produced in the chloroplasts during the conversion of sunlight, carbon dioxide, and water into glucose and oxygen. The oxygen generated is then released into the atmosphere through small openings called stomata on the leaves. Additionally, some oxygen is used in cellular respiration, where it helps convert glucose into energy for growth and other vital functions.
