sacs
Where does Chlorophyll reside in?
In the thylakoid membranes of the chloroplast
What is the photosynthesis chemical equation?
6 CO2 + 12 H2O + light energy —> C6H12O6 + 6 O2 + 6 H2O
What does chloroplast split to get hydrogen and oxygen atoms?

What is carbon fixation?
When carbon is incorporated into organic compounds
What is needed by the Calvin cycle? And where does it get it?
NADPH and ATP; from the light reactions
