The ovule in which the funicle,chalaza and micropyle lie in one vertical plane is called:

How many embryo sacs are present in $100$ mature female gametophytes?

Which type of embryo sac is found in Capsella?

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 $Capsella$,the functional megaspore is always located at the........

Assertion : In hemianatropous ovule,the funicle lies parallel to body of ovule.
Reason : Here,body of ovule is rotated by $90^o$.
