The process of cellular respiration is achieved in plants by the process of photosynthesis. The energy from glucose is derived in this process. The steps of the cellular respiration includes the glycolysis, the kreb's cycle, and the oxidative phosphorylation. During this process, the proton concentration builds in the thylakoid space of the plant cell.
Stomata are normally opened during the day because photosynthesis happens during the day. The stoma allow oxygen and carbon dioxide to diffuse through them.
