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.
photo – synthesis
What is involved with photosynthesis?
Water (H2O)
Carbon Dioxide (CO2)

Lets Write the Reaction 2 Ways
Synthesis or Digestion?
Is energy stored or released?
What kind of reaction is photosynthesis?
Synthesis
Stored
The Chloroplast
What organelle does photosynthesis?
Chlorophyll is a pigment that absorbs light.
Chlorophyll
• Chlorophyll reflects green light.
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!
