Inside the cells of a leaf photosynthesis occurs. specifically, it takes place in the chloroplast of the leaf cell. when solar energy hits the leaf it excites electrons within the chloroplast. this energy allows for water and carbon dioxide to create the products of photosynthesis which are

The products of photosynthesis are sugar molecules (glucose) and oxygen. Photosynthesis is the process in which light energy is converted to chemical energy. In this process, water and carbon dioxide combined with light energy produce glucose molecules (or other sugars) and oxygen is released as a byproduct. The glucose molecules provide organisms with two crucial resources: energy (glucose contains chemical energy) and fixed organic carbon atom. The energy of glucose is used in the process called cellular respiration where adenosine triphosphate-ATP is generated.

It would be cell respiration
