Quick Review
1. Where does photosynthesis happen?
2. Where do the light reactions happen?
3. What are the reactants and products of the light reactions?
Where does it happen?
• Two Stages:– Light Cycle:
– Calvin Cycle:
Takes place in the thylakoid
Takes place in the stroma
Light-Dependent Cycle
• Reactants:
• Products:
H2O and Light energy from the environment
NADP+ and ADP+ from the Calvin cycle.
O2 gas – released through stoma
ATP and NADPH – to Calvin cycle
Calvin Cycle
• Reactants:
• Products:
CO2 – from atmosphere
ATP & NADPH – from light cycle
Sugar & other monomers for macromolecules such as amino acids (proteins) and fatty acids (lipids)
Making Connections
• Look in your book on page 120 and find out what “carbon fixation” is.
• Look up “nitrogen fixation” in your glossary.
• How are these two similar?
Stomata
• Stomata (plural) stoma (singular):Specialized cells that create a pore in the leaves that allow air (CO2, O2, water vapor) to come and go.
Diffusion in Action
With your partner – think/pair/share• Describe why plant cells may want to
close their stoma.
