Both photosynthesis and cellular respiration are extremely important biological processes needed by organism, to carry out their life process.



  • Photosynthesis is a processes by which plants convert light energy to chemical energy. This energy is released during cell activities of the organism.

  • photosynthesis is also largely reponsible for producing and maintaining the oxygen content of the earths atmosphere.

  • it also supplies organic compounds used to build the biological materials used by humans such as wood, cotton and wool.

  • it is the main process by which new energy becomes available to life on Earth.

  • it is also the source of energy stored in fossil fuels. Fossil fuels usually result from the decomposition of buried organisms without oxygen.

Cellular respiration is a set of metabolic reactions and processes that take place in the cells of organisms to convert biochemical energy from nutrients to ATP.

Cellular respiration is one of the key ways a cell releases chemical energy to fuel cellular activities.

The chemical energy stored in ATP is used to drive processes requiring energy including biosynthesis, locomotion or transport across cell membranes.
