1. KEY CONCEPT The overall process of photosynthesis produces sugars that store chemical energy.

2. What do film, radio, television, and music-recording producers do?
They oversee production of something they do not actually make 
How does this relate to photosynthesis?
Plants do not make energy; they capture it, store it, and deliver it.
What law says that energy can be transformed but never created or destroyed?
first law of thermodynamics

3. Vocab:
Photosynthesis
Chlorophyll
Thylakoid
Light dependent reactions
Light independent reactions

4. Photosynthetic organisms are producers.
Producers make their own source of chemical energy.
Plants use photosynthesis and are producers.
Photosynthesis captures energy from sunlight to make sugars.
Photosynthesis: Process through which light energy is captured and used to build sugars that store chemical energy

5. Chlorophyll is a molecule that absorbs light energy.
chloroplast
leaf cell
leaf
In plants, chlorophyll is found in organelles called chloroplasts.

6. Photosynthesis in plants occurs in chloroplasts.
Photosynthesis takes place in two parts of chloroplasts.
grana (thylakoids)
stroma
chloroplast
stroma
grana (thylakoids)
Thylakoids: contain chlorophyll and other light absorbing molecules

7. The light-dependent reactions capture energy from sunlight.
take place in thylakoids
water and sunlight are needed
chlorophyll absorbs energy
energy is transferred along thylakoid membrane then to light-independent reactions
oxygen is released

8. The light-independent reactions make sugars.
take place in stroma
needs carbon dioxide from atmosphere
use energy to build a sugar in a cycle of chemical reactions

9. The equation for the overall process is:
6CO2 + 6H2O  C6H12O6 + 6O2
C6H12O6
granum (stack of thylakoids)

stroma (fluid outside the thylakoids)

10. Due at the end of class:
Read “Artificial Photosynthesis” on page 104. Answer the following questions:
How is the nanowire array similar to a chloroplast? How is it different?
Can you think of a device that converts solar energy to electrical energy?
If solar energy from artificial photosynthesisis to be a major energy source, it must be stored so it is avail;able at all times. In plant photosynthesis, the solar energy is stored in the chemical bonds of glucose. How could solar energy from artificial photosynthesis be stored
