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-$I$	Column-$II$
$(a)$ Sporopollenin	$(1)$ Spindle-shaped nucleus
$(b)$ Cellulose,Pectin	$(2)$ Exine
$(c)$ Vegetative cell	$(3)$ Intine
$(d)$ Generative cell	$(4)$ Irregularly shaped nucleus

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.
