Examples from literature

• As a rule the embryo is very small and surrounded by abundant endosperm. 
• In cases where the embryo has stored reserve food within itself and thus provided for self-nutrition, such endosperm as remains in the seed may take on other functions, for instance, that of water-absorption. 
• The formation of endosperm starts, as has been stated, from the endosperm nucleus. 
• The function of the endosperm is primarily that of nourishing the embryo, and its basal position in the embryo-sac places it favourably for the absorption of food material entering the ovule. 
• This apparently profitable machine permitted the miller to efficiently separate wheat flour into three components: bran, germ and endosperm.
