For pollinated ovary which is correct
Accessory cells are diploid
Antipodal cells are haploid
Egg cell is diploid
Ovule cell is haploid
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
$A$ : Filiform apparatus guides the pollen tube into the synergids.
$R$ : It is special cellular thickening at micropylar tip to secrete chemotropic stimulus.
The number of mitotic generations required to form a mature embryo sac in most of the flowering plants is
Synergids of the polygonum type embryo sac are
The number of embryo sac in an ovule is generally
