Photosynthesis and respiration are two the important processes happening in plants. In the process of photosynthesis green plants form simple sugars in the presence of sunlight.  As a part of the reaction, they release oxygen into the atmosphere. Oxygen produced as a result of photosynthesis, gets used up by the plants during respiration. Carbon dioxide gas produced as a result of respiration is used up during photosynthesis. Thus, the waste released by both photosynthesis and respiration are used up by each other.
