lyrics of Paparazzi by Lady Gaga to memorize facts about Double Fertilization




I modified the lyrics of Paparazzi by Lady Gaga to memorize facts about Double Fertilization and Formation of Embryo Sac. Hope you guys enjoy...
(Sorry for the poor sound quality.)

Background song: Paparazzi [Lady Gaga]
P.S. : I don't own any of the copyright for the background song.

Pollen tube reach ovary and it
penetrates ovule through the micropyle
Tube nucleus in front, generative nucleus behind
Tube nucleus at end of pollen
tube disintegrates, leaving a clear passage
for 2 male nuclei to enter embryo sac
'Coz you know that after that

1 of male nuclei moves to egg cell nucleus and fuse with it
To form diploid zygote
Other male nucleus fuse with 2 polar nuclei to form
Triploid, triploid nucleus
Triploid nucleus divides to form endosperm that provides food
Products of double fertilization are diploid zygote
And triploid nucleus

Embryo sac originates from
Embryo sac mother cell that undergoes meiosis
to create 4 haploid cells called megaspores
3 of the 4 megaspores disintegrates
While the fourth cell grow
and develops to create embryo sac
Its nucleus undergoes mitotic division 3 times

To produce 8 haploid nuclei with 4 nuclei at each
end of embryo sac
1 nucleus from each end of embryo sac migrates to centre
To form 2 polar nuclei
3 nuclei migrate to 1 end of embryo sac
To form 3 antipodal cells
A+ BIOLOGY!

Another 3 migrate to opposite end
of embryo sac to produce
2 synergid cells with an egg
It's the end but we still have fun

Mature embryo sac will have have 3 cells at each end with
2 nuclei in centre
All of them haploid but only 1 at end of micropyle
will form the ovum
3 antipodal cells and 2 synergid cells disintergrate
That is all you have to know about the embryo sac
Bye bye, jumpa lagi!
