In which part of the flower does meiosis occur?

Answer 1

In any flower the process of meiosis occurs only in the reproductive parts as explained below.

1) Meiosis that occurs in ANTHERS-

Each anther has two anther lobes .Each one of them contains DIPLOID pollen mother cells. They undergo MEIOSIS to form HAPLOID pollen grains ( also called microspores.)

These pollen grains are then carried away during pollination and germinate on the stigma of a carpel to form a pollen tube and male gametes.

2) Meiosis that occurs in the OVULE- it contains a tissue called Nucellus ( no spelling mistake here.) protected by integument/s.

Only one cell of the multicellular and DIPLOID nucellus undergoes MEIOSIS to form 4 HAPLOID megaspores.

Out of these 4 only one survives and forms ' Embryo Sac' in which fertilization occurs.

I hope you have basic information about a flower .

Answer 2

In two places: in the megasporangia (the cells that will become the egg cells in the ovules of the ovary) and in the microsporangia (the cells that will give rise to pollen).

Answer 3

In the reproductive cells and parts

Answer 4

in reproductive cells

Answer 5

I think as it's blooming.
