Cellular respiration cannot occur without photosynthesis, and photosynthesis certainly cannot occur without the help of its partner. Home Photosynthesis and Respiration. Photosynthesis and Respiration The relationship between photosynthesis and cellular respiration is such that the products of one system are the reactants of the other. Below are some of the similarities and differences between these two systems.

In respiration, energy is released. The raw materials of respiration are carbohydrates or organic substances and oxygen.
The oxygen is used and carbon dioxide is released in the process of respiration. Chlorophyll is green because the light required for photosynthesis is red and blue light, leaving green light to be reflected back to our eyes. Photosynthesis occurs in the leaves of plants with little to none in the stems. Plant leaves are made of upper and lower epidermises, mesophyll, veins, and stomates. Mesophyll is the layer of the plant that contains chloroplasts and is the only place photosynthesis occurs.
The energy taken is stored as ATP adenosine triphosphate. It is required for energy storage and is made of the nucleotide adenine with ribose sugar. The respiratory system allows living creatures that are not plants to obtain oxygen from the air for use in the blood and cells. Oxygen is a much needed nutrient and living organisms can roughly only survive for minutes without it. Even if oxygen flow is reestablished, the damage can be irreparable. Alveoli are responsible for exchanging oxygen rich air with carbon dioxide rich blood cells.
