In given figure, labeled part $X$ is formed by....
$PMC$
Megaspore Tetrad
Microspore
Megaspore
$X$ - $MMC$ is a large cell containing dense cytoplasm and a prominent nucleus
$Y$ - Method of embryo sac formation from a single megaspore is termed monosporic
Synergids are which type ?
Embryo sac is also known as
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
In angiosperms, functional megaspore develops into
