Photosynthesis Photosynthesis is a process in which make their own food from their light and release oxygen. Photo means light  Photosynthesis use light energy change their chemical energy store in starch. Photosynthetic organisms is known as photoautotrophs. Photosynthesis is important due to to process food is primary source  on earth  release of oxygen is responsible for the atmosphere. Feature of photosynthesis Physio chemical process Redox process Up hill process Endergonic process. Physicochemical process Light energy is converted into glucose/starch. Light energy is physical form. Starch or Glucose is chemical form. Redox process Light reaction is oxidation process and  dark reaction is reduction process. Light reaction is a splitting of water. Dark reaction is CO2 (carbon dioxide) fixation. Uphill process Carbon dioxide is a weak electron acceptor. Electron move like in upward direction. Endergonic process Energy in which consumption in the form of light. Equ...
