In plants, the light dependent reactions take place in the thylakoid. The light reactions are so called because in this set of reactions, light energy is transformed into chemical energy carried by two compounds ATP, and NADPH. These compounds are used for the next set of reactions, often called the dark reactions of the Calvin Benson cycle.

The diagram above shows the major "cast members" for the light reactions.  Clicking on a hot spot gives a brief narrative about what's going on in that part of photosynthesis.
