EXERCISE 16 



The work which any organ performs or the way it behaves in relation to the plant or animal of 

 which it is a part is called its functions. Some organs perform no functions useful to the organism. 

 Human beings make use of various parts of plants and animals. This use may or may not have anything 

 to do with the function of the part. 



In the following tables indicate the uses to which we can put the ten named organs of certain 

 animals or plants and the functions of these organs in the life of the organism.
