PHOTOSYNTHESIS PHOTOSYNTH ESIS Energy Forms of Energy Photosynthesis requires LIGHT Energy AND CONVERTS LIGHT TO Chemical/compounds the bonds. contain energy in CELLULAR ENERGY Chemical energy created to make glucose in photosynthesis from ATP and NADPH+ ENERGY OF LIGHT Visible Light – ROYGBIV Some absorbed by pigments in plants Chlorophyll main pigment – found in the thylakoids ABSORPTION OF LIGHT QUESTIONS WHY ARE PLANTS GREEN? WHAT WOULD HAPPEN TO A PLANT PLACE UNDER YELLOW LIGHT? WHAT WAVELENGTH TO PLANTS GROW BEST? PHOTOSYNTHESIS From the atmosphere From Soiltranspiration BECOMES BIOMASS OF PLANT OR USED FOR ENERGY IN CELLULAR RESPIRATION SUN POWERS THE ECOSYSTEM Two reactions of photosynthesis Light dependent reaction Calvin cycle (sometimes called light-independent reaction) ORGANELLE OF PHOTOSYNTHESIS Light dependent reaction Inside the thylakoid – contain photosynthetic pigments –main chlorophyll. INPUT: WATER AND LIGHT OUTPUTS: OXYGEN (WASTE) AND HIGH ENERGY COMPOUNDS – ATP AND NADPH+ Energy will be used in the Calvin Cycle CALVIN CYCLE HAPPENS IN THE STROMA (AQUEOUS) INPUT: ATP AND NADPH+ (ENERGY), AND CARBON DIOXIDE OUTPUT- GLUCOSE What are the reactants of the light independent reaction? Products? What about the Calvin cycle?
