Only the non-functional megaspore develops into female gametophyte

The functional megaspore undergoes

In angiosperms, functional megaspore develops into

In angiosperms, functional megaspore develops into

Development of male gametophyte is :-

What will be the ploidy of cells of nucellus, MMC, functional megaspore and female gametophyte?

Which one is female gametophyte

The functional megaspore referred to as :

What is meant by monosporic development of female gametophyte?

Which of these plants is correctly matched with its reproductive characteristics ? (i) Sphagnum : Male sex organ called antheridium produce biflagellate antherozoids while the female sex organ called archesporium produces a single egg . (ii) sequoia : One of the megaspores enclosed within the megasporangium develops into a multicellular female gametophyte that bears two or more archegonia or female sex organs (iii) Wolffia : one of the male gametes fuses with the egg cell to from a zygote while the other male gamete fuses with the diploid secondary nucleus to produce the triploid primary endosperm nuclelus . (iv) polysiphonia . Sexual reproduction is oogamous with non-motile gametes and accompanied by complex post-fertilization developments

In gymnosperms, the microspores develop into a male gametophytic generation which is 1 highly developed and is made of large number of cells 2 semi- / parasitic 3 free living 4 highly reduced and is confined to only a limited number of cells.
