Vedclass · Answer

(B) In angiosperms,double fertilization involves two fusion events. One male gamete fuses with the egg cell to form a diploid zygote. The second male gamete fuses with the two polar nuclei (or the secondary nucleus) located in the central cell. This process is known as triple fusion,and the resulting triploid structure is called the Primary Endosperm Nucleus $(PEN)$. The $PEN$ subsequently develops into the endosperm,which provides nourishment to the developing embryo.

The fusion product of polar nuclei and a male gamete is:
