You should have done all this before the time was almost up!

Short verison:

Photosynthesis occurs in two stages.

In the first stage, light-dependent reactions or light reactions capture the energy of light and use it to make the energy-storage molecules ATP and NADPH.

During the second stage, the light-independent reactions use these products to capture and reduce carbon dioxide.


Most organisms that utilize photosynthesis to produce oxygen use visible light to do so, although at least three use infrared radiation.
