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

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
