Vedclass · Answer

(A) Double fertilisation is a characteristic feature of angiosperms,discovered by $SG$ Nawaschin in $1898$.In double fertilisation,one male gamete fuses with the egg cell (ovum) to form a diploid zygote $(2n)$.The second male gamete fuses with the diploid secondary nucleus (central cell) to form the triploid primary endosperm nucleus $(3n)$,which develops into the triploid endosperm.The endosperm provides nutrition to the developing embryo.Therefore,statements $I$ and $II$ are correct.

Column-$I$ (Pre-fertilization)	Column-$II$ (Post-fertilization)
$P$. Ovule	$I$. Fruit
$Q$. Integument	$II$. Embryo
$R$. Ovary	$III$. Seed
$S$. Ovary wall	$IV$. Pericarp
$T$. Zygote	$V$. Seed coat

Angiospermic plants are characterised by:
$I.$ Double fertilisation
$II.$ Triploid endosperm
$III.$ Diploid endosperm
