Photosynthesis
Standards
• CLE 3210.3.3 Investigate the
relationship between the processes of
photosynthesis and cellular respiration.
• SPI 3210.3.3 Compare and contrast
photosynthesis and cellular respiration
in terms of energy transformation.

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:
Takes place in the thylakoid
– Calvin Cycle:
Takes place in
the stroma
Light-Dependent Cycle
• Reactants:
H2O and Light energy from the
environment
NADP+ and ADP+ from the
Calvin cycle.
• Products:
O2 gas – released through
stoma
ATP and NADPH – to Calvin
cycle
Calvin Cycle
• Reactants:
CO2 – from atmosphere
ATP & NADPH – from light cycle
• Products:
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.
