Question

difference between photosynthesis and respiration ​

Answer 1

Photosynthesis

Photosynthesis converts light energy into chemical energy, and stores it in sugar. This process occurs in the chloroplasts, using chlorophyll. The chemical formula for the process requires six molecules of carbon dioxide and six molecules of water plus the energy from light. This creates a sugar chain and six units of oxygen. Chlorophyll is green because the light required for photosynthesis is red and blue light, leaving green light to be reflected back to our eyes.

Respiration

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. Diffusion occurs due to the pressure difference between alveoli, which is high, and the pressure of blood, which is lower. Blood cells take the oxygen and alveoli take the carbon dioxide, which is then exhaled.
