Photosynthesis Basics
Where does photosynthesis take place?
In organelles called chloroplasts.
![Page 10: Ch. 6 Photosynthesis](https://reader035.vdocuments.us/reader035/viewer/2022062218/5681625b550346895dd2ad32/html5/thumbnails/10.jpg)
Chlorophyll
•Chloroplasts contain the pigment known as chlorophyll
![Page 11: Ch. 6 Photosynthesis](https://reader035.vdocuments.us/reader035/viewer/2022062218/5681625b550346895dd2ad32/html5/thumbnails/11.jpg)
Pigments
•Absorb different wavelengths of light (colors)•Reflect (transmit) what they do not
absorb•We see what is reflected back.

Light Reactions
Reactants:
Products:
Light in the form of photons, water,
NADP+, ADP, Phosphorous
ATP, NADPH, oxygen
![Page 16: Ch. 6 Photosynthesis](https://reader035.vdocuments.us/reader035/viewer/2022062218/5681625b550346895dd2ad32/html5/thumbnails/16.jpg)
What you need to know:
• Where do the light reactions occur?
• What is needed?
• What is created?
In the thylakoids that are inside chloroplasts.
Light (photons), water
ATP & NADPH go on to Calvin cycle; and oxygen that is released.

Where does it happen?•Two Stages:
• Light Cycle:
• Calvin Cycle:
Takes place in the thylakoid
Takes place in the stroma
![Page 28: Ch. 6 Photosynthesis](https://reader035.vdocuments.us/reader035/viewer/2022062218/5681625b550346895dd2ad32/html5/thumbnails/28.jpg)
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
![Page 29: Ch. 6 Photosynthesis](https://reader035.vdocuments.us/reader035/viewer/2022062218/5681625b550346895dd2ad32/html5/thumbnails/29.jpg)
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 ConnectionsTogether
•How do the light-dependent and light-independent cycles of photosynthesis depend on each other?
![Page 32: Ch. 6 Photosynthesis](https://reader035.vdocuments.us/reader035/viewer/2022062218/5681625b550346895dd2ad32/html5/thumbnails/32.jpg)
Making ConnectionsTogether
•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?
![Page 33: Ch. 6 Photosynthesis](https://reader035.vdocuments.us/reader035/viewer/2022062218/5681625b550346895dd2ad32/html5/thumbnails/33.jpg)
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.
![Page 34: Ch. 6 Photosynthesis](https://reader035.vdocuments.us/reader035/viewer/2022062218/5681625b550346895dd2ad32/html5/thumbnails/34.jpg)
