                The role of double fertilization in angiosperms is to produce:                                                         

    A)              endosperm   

    B)              integuments

    C)              cotyledons 

    D)              Endocarp

    Correct Answer: A

    Solution :

                Usually, fertilization of female egg by male gamete results in the formation of zygote. In angiosperms, however, a second fertilization of secondary polar nucleus by another male gamete leads to the formation of triploid primary endosperm nucleus. This nucleus is divided by successive or simulataneous type of division and forms a multicellular structure called as endosperm which provides nutrition to developing embryo.
