A. Cellular respiration

B. Photosynthesis

EXPERT ANSWER

(B) Photosynthesis is the process that results in the production of oxygen. Photosynthesis is a process that involves light-dependent reactions, and it occurs mostly in green plants and also in some organisms by the utilization of water and CO2 to produce oxygen. A Biology course will help students understand photosynthesis.

The photosynthesis process produces oxygen. Plants use carbon 11 oxides (and water (H20) from the soil and air during the process. Within the plant cell, carbon dioxide is reduced, and the water is oxidized. Photosynthesis transforms carbon dioxide into glucose and water into oxygen.
