Vedclass · Answer

(C) Double fertilization is a characteristic feature of angiosperms. It was discovered by $S. G. Nawaschin$ in $1898$.In double fertilization,one male gamete fuses with the egg cell to form a diploid zygote,and the second male gamete fuses with the diploid secondary nucleus to form the triploid primary endosperm nucleus $(PEN)$.Since the secondary nucleus is diploid $(2n)$ and the male gamete is haploid $(n)$,the resulting primary endosperm nucleus is triploid $(3n)$.Therefore,the statement that the endosperm nucleus is diploid is incorrect.The endosperm provides nutrition to the developing embryo.
