Which statement summarizes the main purpose of photosynthesis? it converts gases to solids in the form of sugar. it converts carbon to oxygen. it converts light energy to chemical energy. it converts energy to mass.

The correct answer is It converts light energy to chemical energy. That is because creation of oxygen is not done for us, the plants don't really care. The oxygen created is a side addition to the fact that plants create energy for themselves. They take light energy and convert it into energy for themselves made out of chemicals, oxygen being their waste that we use.
