In angiosperms, the following events occur during megasporogenesis and megagametogenesis
$(i)$ Differentiation of megaspore mother cells
$(ii)$ Meiosis of the megaspore mother cell
$(iii)$ Formation of a linear tetrad
$(iv)$ Mitotic division of the functional megaspore
$(v)$ Degeneration of 3 megaspores
$(vi)$ Formation of embryo sac
$(vii)$ Fusion of polar nuclei
The correct sequence is
$v, i, ii, vi, vii, iii, iv$
$iv, iii, vii, vi, ii, i, v$
$v, i, ii, vii, vi, iv, iii$
$v, i, ii, vi, vii, iv, iii$
Egg apparatus of angiosperm consists of
If the endosperm mother cell of an angiosperm plant has $24$ chromosomes, the same in the $MMC$ will be
