Vedclass · Answer

(C) The figure represents a mature embryo sac (female gametophyte) of an angiosperm. - Part $a$ points to the finger-like projections at the micropylar end of the synergids,known as the filiform apparatus. - Part $b$ points to the two synergids located at the micropylar end. - Part $c$ points to the two polar nuclei located in the central cell. - Part $d$ points to the three antipodal cells located at the chalazal end. Therefore,the correct sequence is $a$: Filiform apparatus,$b$: Synergids,$c$: Polar nuclei,$d$: Antipodal cells. This matches option $C$.

Column $I$	Column $II$
$(a)$ Sex cell	$(1)$ Synergid cells
$(b)$ Synergid cell	$(2)$ Antipodal cells
$(c)$ Cell opposite to micropyle	$(3)$ Egg cell
$(d)$ Central cell	$(4)$ Secondary nucleus

Examine the figure given below and select the right option identifying all the four parts $a, b, c$ and $d$.
