1. KEY CONCEPT The overall process of photosynthesis produces sugars for plant that store chemical energy by absorbing sunlight in chloroplasts

2. Photosynthetic organisms are producers.
Producers make their own source of chemical energy.
Plants use photosynthesis and are producers (also called autotrophs).
Photosynthesis captures energy from sunlight to make sugars for themselves
6CO2 + 6H2O  C6H12O6 + 6O2
in sunlight

3. Chlorophyll is a molecule that absorbs light energy from sun.

In plants, chlorophyll is found in organelles called chloroplasts.

4. Photosynthesis in plants occurs in chloroplasts.
Photosynthesis takes place in two parts of chloroplasts.
AT BOTTOM OF YOUR NOTES:
light reactions = in thylakoid
Capture and transfer energy;
Need water, produce oxygen for us to breathe
light independent or dark rxns= in stroma
Need carbon dioxide, produce sugar

grana (thylakoids)

5. The equation for the overall process is:
6CO2 + 6H2O  C6H12O6 + 6O2

6. 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

7. 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
