MODELING PHOTOSYNTHESIS REVIEW
Photosynthesis Review
Chemical Potential Energy Diagram
Provides energy
Endothermic
Glucose = Stored Chemical PE
Importance of O2
Skip 5 and 6
• Too complicated for our purposes• If you care – take AP Bio
7. Lots of things can be made from sugar
Where Does a Plant Get It’s Mass
• Not from water…. H2O O2 gets breathed out
• Not really from the soil
Most Mass Comes from CO2!

• Glucose production (hard to really measure, remains in plant)
• Oxygen production• CO2 consumption• Water consumption (hard to really measure as
there is a TON of water)• Indirectly – how much a plant grows
7.
Virtual Labs
• Work as a group, though each person should work through own paper
• If you don’t finish each person should finish individually
• Expect exit slip on Tuesday
• Review Unit Objectives and Level I/II/III expectations
