Answer:
Both organs exchange oxygen and carbon dioxide.
Explanation:
This is because the plant leaf exchange gases during photosynthesis where it uses carbondioxide and water in the presence of light energy and chlorophyll to produce carbohydrates and oxygen. Therefore oxygen is given out to the atmosphere and carbondioxide is taken in.
The lungs also is an organ of respiration, it is where exchange of gases take place where oxygen is taken in through breathing and carbondioxide is given out as by product.
