Photosynthesis Harnessing Energy For All!
photo – synthesis • What does photo mean? • light • What does synthesis mean? • Making big things from small things. • Put it together and you get things being made from light. • Where does the energy from the sun go? What is being made? • Into glucose.
What are the reactants of photosynthesis? Carbon Dioxide (CO2) Water (H2O)
What are the products of photosynthesis? Oxygen (O2) Glucose (C6H12O6)
What kind of reaction is photosynthesis? • Synthesis or Digestion? • Is energy stored or released? Synthesis Stored
What organelle does photosynthesis? • The Chloroplast
Chlorophyll • Chlorophyll is a pigment that absorbs light. • Chlorophyll reflects green light.
Photosynthesis • Plants are Autotrophs. Autotrophs harness energy from an abiotic source. • What source of energy do Autotrophs tap into? • The SUN! • Plants are Producers. Producers harness carbon from an abiotic source. • What source of carbon do Producers tap into? • Carbon Dioxide!
