What is th inter relationship between photosynthesis and cellular respiration?

Photosynthesis and cellular respiration are the opposite of each other, but the first answer isn't correct. Photosynthesis is how plants make their own food (sugars and starch) from CO2 and release oxygen as a waste product. Cellular respiration takes in sugar and oxygen and the releases CO2. Plants do both.What is th inter relationship between photosynthesis and cellular respiration?Photosynthesis and cellular respiration are basically the opisite of each other. Photosynthesis, as most people know, is the process of plants taking in CO2 (Carbon Dioxide) and using it as energy/ food. Then cellular respiration is the process of plants releasing O2 (oxygen) back into the atmosphere.
