If the number of chromosomes in root cells is $14$,what will be the number of chromosomes in synergid cells of an ovule of that parent?

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:

An orthotropous ovule is one in which the micropyle and chalaza are:

Which structure is present in the ovule?

What is the function of the micropyle in an ovule?

Megaspores are produced from the megaspore mother cells after
