What is the importance of photosynthesis and cell respiration?
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.
