• When thinking about photosynthesis, think about what it takes to keep a plant alive:

  • what goes in: water, light, and carbon dioxide

  • what goes out: oxygen and sugar
    
    

​

What goes in and what goes out?

• ​Reactants: what goes into the equation

  • Carbon dioxide (CO2)

  • Water (H2O)

  • Light energy (from the sun)
    

​

• Products: what goes out of the equation

  • glucose (C6H12O6)

  • Oxygen (O2)
