Respiration is related primarily to the release of energy in protoplasm. It is carried on by every 

 living cell. In many-celled organisms we find a variety of structures and processes related to respiration. 

 Respiration involves an intake and an output of gases. In the spaces below tell briefly what structures 

 and processes are involved in the respiration of the named organism and in the respiration of the 

 individual cells mentioned.
