Answer 2

A reason is that multicellular organisms need special organs for exchange of gaseswith the environment because of prokaryotic cells found in the body. The cells are not in contact with the environment and therefore diffusion would not work in the exchange of gases. The organs in the body therefore serve this purpose.
