between plants and people is made possible by the differences between cellular respiration and photosynthesis. While cellular respiration occurs in all living organisms‚ photosynthesis relies on chlorophyll and is unique to plants‚ algae‚ and some bacteria. Respiration and photosynthesis are essentially the same process in reverse.
