Double Fertilization no normal
definition of fertilization we say that
the pollen grains or you can say the
male gamete meets the egg female gamete
and their fusion which result in the
formation of embryos Zygot and the see
this is the normal definition of fertile
age then what is Double Fertilization
when I say double fertilize it means
that there are two male gametes and
these two male gametes are haploid when
I say haploid it means they have 23
number of chromosomes this to me haploid
male gametes will fuse with two female
haploid gametes during the process of
double fertilization what happens is
there are two male gametes which are
haploid and one of the haploid male
gamete fuses with the egg which founds
the zygote or we can see the seed and
another haploid male gamete or pollen
grain fuses with the prime polar witness
and then it fuses with the floral
necklace
it forms primary endospore and this
primary endosperm this is nothing but
the seed code which you see in seeds
which provides nourishment to the
growing embryo so when I will take a
scene and remove seed code that is the
primary endoscope so during the process
of double fertilization one mil gamete
fuses with the egg and another mill
gamete fuses with the polar needless
sense of this process to different male
gametes fuses with one with the egg
another with the polar nuclei in the
same ovary this process is called as
double fertilization now then the male
gametes means the egg it is called as
single whereas doing Singam II serious
form fertilization is taken place
whereas when two Pollard nucleus meets
one male gamete together they will form
3 sets and then three sets of form it is
also called as triple fusion Singam II
has various aspects or it helps the
plants in better way to kuru whereas
triple fusion helps to provide triple
endosperm and this end
form is nothing but providing
nourishment to the growing em do
double fertilization by this persistence
college double education since both the
male gametes take part in the process of
fertilization which occur at two
different places in the same embryo or
against the ovary now among them one
male a gamete or one haploid male gamete
when I say haploid it means to entry
number of chromosomes and half number of
chromosomes the pollen grain makes the
egg which is also happier contains 23
number of chromosomes to form the egg
cell or it gives it a Saigon on the sea
which will be nothing but diploid and
this process is called as sin
brilliant double fertilization one male
gametes fuses with the egg to Holmes I
got or you can say this week whereas the
second Milly gamete fuses with the two
polar nucleus so together there will be
three cells on three different entities
to form a triploid primary endosperm or
you can sing simple language the seed
and this seed core is the food for the
growing embryo or seed and an analyst it
has developed tumors radicals to absorb
nutrients from the soil sin gamma is
also called as double fertilization
against a double fertilization process
also includes cilia which helps in
better growth of the plant also help to
convert plant or scene into a diploid
state students now will be seen how does
the process of double filtration take
this diagrammatically as you can see in
the diagram this is the female
gametophyte which consists of stigma
style and opening inside this there are
antipodal cells which are accessory
since we all know the two polar nucleus
which will form the triploid family and
of spawn it consists of xn so didn't
process of double fertilization what
happens is the two mini gamete or you
can see the two pollen grains among this
one pollen grain will fuse with the One
X cell to form seed siphon and this
process is finest singham whereas
another pollen grain or the second
Poland green will fuse with the polar
nucleus and together they will form 1 2
& 3 cells which is triploid primary
Angus form and this process is called as
triple fusion in simple language we can
say that Singam II plus triple fusion is
equal to double fertilization which will
help to form a seed I hope you looked
clear with the concept of double
fertilization and how does double
fertilization takes place thank you
