Distinguish, differentiate, compare and explain what is the difference between Photosynthesis and Respiration.

Comparison and Difference between Photosynthesis and Respiration

  1. Photosynthesis occurs only in Chlorophyll containing cells of plants. Respiration occurs in all plants and animal cells.
  2. Photosynthesis  takes place only in the presence of light. Respiration takes place continually both in light and in the dark.
  3. During photosynthesis, radiant energy is converted into potential energy. During respiration, potential energy is converted into kinetic energy.
  4. In photosynthesis, sugar, water and oxygen are products. In respiration, CO2 and H2O are products.
  5. First one synthesizes food. Second one oxidizes food.
  6. In the first, CO2 and H2O are raw materials. In the second, O2 and food molecules are raw materials.
  7. Photosynthesis is an endothermal process. whereas the other is a exothermal process.
  8. Photosynthesis stores energy. Respiration releases energy.
  9. In the first, it includes the process of hydrolysis, carboxylation etc. In the seocnd, tt includes the process of dehydrolysis and decarboxilation etc.
  10. Photosynthesis results in an increase in the weight. Respiration results in a decrease in weight.
  11. Photosynthesis is an anabolic process. Respiration is a catabolic process.
  12. Both the process  requires cytochrome.
