Oxygen is produced by a light reaction in plants. This reaction is called Photosynthesis. During photosynthesis, a plant will absorb sunlight and carbon dioxide and convert it into energy and oxygen.

Oxygen is not important in photosynthesis. The gas used in photosynthesis is Carbon Dioxide. Oxygen is only produced as a waste product of the reaction. The equation for photosynthesis is:Carbon Dioxide + Water (+Sunlight)--> Glucose + Oxygen

As you can see, Oxygen is not needed for photosynthesis, but is simply produced as a waste product.Perhaps you were thinking about respiration, for which oxygen is very important.

The products of the light reactions are mainly energy so the plant can continue to do the complete process of photosynthesis.

What is produced by the reaction of light-dependent?

During light dependent reaction photolysis of water takes place resulting in to the formation of energy rich compounds like NADPH2 and ATP from NADP and ADP. Oxygen is liberated as a bye-product.
