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.
After carbon dioxide enters the leaf through stomata it moves into the mesophyll cells where photosynthesis occurs and glucose is constructed. Respiration. Photosynthesis is the process by which plants use light energy to convert carbon dioxide and water into sugars. The sugars produced by photosynthesis can be stored, transported throughout the tree, and converted into energy which is used to power all cellular processes.
