process of plant ovule formation

• what is found within the nucellus in the formation of the ovule

  the megaspore mother cell
• what happens to the megaspore mother cell in the nucellus

  it will undergo meiosis to produce4 haploid megaspores
• what are the 4 haploid megaspores known as

  a tetrad of 4 haploid cells
• by what process does the megaspore mother cell turn into 4 haploid megaspores

  meiosis
• what will happen to the 4 haploid megaspores that are produced from the megaspore mother cell


  three will degenerate and one will grow and develop
• what will happen to the one haploid megaspore that survives whilst the other 3 degenerate

  the last megaspore will undergo three mitotic divisions
• what will be produced from the surviving haploid megaspore undergoing 3 mitotic divisions

  8 haploid nuclei
• where will the 8 haploid nuclei that is produced from the one surviving haploid megaspore cell be found

  in the embryo sac
