which forms the coat of the fruit, is called the pericarp 

 (Gr. peri = around) . 



The flowers of Stocks are often sweetly scented, especially 

 at night. This attracts night-flying moths, which visit the 

 flowers and search for the pollen and honey. In the process 

 they become dusted with pollen, and, carrying it to other 

 Stock flowers, may deposit grains on the stigma and thus

secure fertilization of the ovules and the formation of seeds, 

 from which a new generation of plants arises. 



From our study of the Stock we learn that the organs of 

 a plant are of two distinct kinds, (1) vegetative organs 

 roots, stems, and leaves which are concerned with obtain- 

 ing food and building up the main body of the plant ; and 

 (2) reproductive organs the flowers whose function is to 

 produce seed, from which arises a new generation of plants.
