Vedclass · Answer

(D) Double fertilisation was discovered by $SG$ Nawaschin $(1898)$ and Guignard in $Lilium$ and $Fritillaria$. Double fertilisation is a characteristic feature restricted to angiosperms.When the pollen tube enters the ovule,it releases two male gametes into the embryo sac.$(i)$ Generative Fertilisation: Fusion of one male gamete with the egg cell to form a diploid zygote $(2n)$.$(ii)$ Vegetative Fertilisation (Triple Fusion): Fusion of the second male gamete with the diploid secondary nucleus (formed by two polar nuclei) to form the primary endosperm nucleus $(PEN)$,which develops into the triploid endosperm $(3n)$.Statement $D$ is incorrect because double fertilisation encompasses both syngamy (fusion with egg) and triple fusion (fusion with polar nuclei),not just the fusion of a male gamete with the egg.
