Photosynthesis and photography both involve light sensitive reactions. The leaves of plants containa green pigment called chlorophyll. This can absorb radiation in the visible region of theelectromagnetic spectrum and use this energy to synthesize chemicals and provide food for theplant.During photosynthesis, plants transform carbon dioxide and water into oxygen and sugars such asglucose:6CO2 (g) 6H2O(l) C6 H2 O6 (aq) 6O2 (g)Δg 2820kJ 2 + 2 → 6 12 6 + 2 = +2820kJIn the absence of sunlight, energy is no longer provided and photosynthesis ceases.Photosynthesis is a/an:
