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.

Angiospermic plants are characterised by:
$I.$ Double fertilisation
$II.$ Triploid endosperm
$III.$ Diploid endosperm
Choose the correct option from the following regarding the above statements.
