are studying chapter  Reproduction
in plants in that we are studying topic
Self Pollination When i say self
pollination self means an individual
flower and when I say pollination
it means transfer of gametes that is
male and female in the same flower
today we'll be studying how it is done.
Self-Pollination if I break that what
self-pollination self means a single
flower which is present on one time and
when I say pollination
it means transfer of gametes so during
the process of self pollination what
happens is the transfer of pollen grains
that is the stigma or we can say the
transfer of pollen grain the male
gametophyte to the female gametophyte
takes place in the same flower in simple
language you can say the transfer of
pollen grains from the anthem a pollen
grain suppressant takes place to this
stigma where the female gametophyte is
present in the same flag so there will
be only one two flower in boiling in one
viscous this process of self pollination
takes place now self pollination can be
of auto kami type or three tone Aoyama
time when this pollination takes place
in one flower that is in one a discus
and hibiscus is present on a single
flower or you can say on a single plant
it is called as Auto kami whereas if the
pollination is taking place between two
flowers which are of same species for
example through different hibiscus both
the same species hibiscus and this both
hibiscus are present at different
position on the same plant it is called
as cheetah Mogami so remember in self
pollination the flowers have to be
present on the same plant where it there
it is Auto kami or whether it is Chetan
again now there are various plants which
do self pollination or you can say
autonomy sunflower is there or it
discusses there's mirabilis is their
sole illumise there there are a lot of
them now for doing self pollination
there are few agencies which are
required and devices that favor self
pollination are homogamy and mr. Ogami
when I say homogamy
the word homo means similar and gammy
means Kamath's so we can understand
something having similar comments maybe
the flowers have similar gametes or one
flower has both male and female gametes
inside its
yes homogamy means both the male and
female gametes are present inside the
same flow
cell formation and the definition of
self pollination goes it is a transfer
of pollen grains from anthem to stigma
of the same flower cell function is also
called as Auto gram
but when transfer of pollen grains takes
place between neighboring flowers
present on the same plants it is coil as
children organ
now to help set pollination process or
pequeno self pollination smoothly there
are two agencies of factors that help
the process of self pollination which
are homogamy and Callisto gamma when I
say homogamy it means by section flowers
and bisexual flowers have both the male
and the female gamete in the same flower
when the other one is kills togami and
includes togami what happens is the
flowers never expose their sex organs
and the pollen grains directly fall on
the stigma and it reaches to the egg but
near the ovary and the process of
fertilization can take this students in
this part of the chapter we have started
about self pollination which takes place
on a single plant in self pollination
there is only one single plant and there
are only flowers which could be of same
species present on that plant I hope you
are clear with the concept of self
pollination thank you
