Reproduction Video Lecture - Class 11

hello students today different discuss
about a sexual reproduction
we have already seen different type of
asexual reproduction budding binary
fission multiple friesen vegetative
propagation artificial and natural
vegetative propagation pore formation
etc now the day we will see vote the
first one else parthenogenesis
if you split this world you will get two
words here parkin plus genus
genesis means production and parkin
these false
so it's a false production or false
reproduction we're offsprings are
produced without fertilizer you can say
it's a modification of sexual
reproduction where add develops into a
complete or gas without any fertilizer
so i can write the definition like this
its production off
complete organs
without fertilization
because there is no mixing of DNA no
mixing of cactus trick feature that's
why it's a uni parental reproduction
and included as a sexual border of D
production
here Axl that is a haploid structure
jeans and characteristic feature if
suppose this one is a human axle then 23
ko's homes have found that undergoes in
mitotic division
angle form md although this embryo is
haploid in each other beam and that give
rise to applied
this is called as parthenogenesis it's
very common in plans but somewhere it's
also found an animal's natural
carcinogenesis is found in honey bee
prepend of bees around enough hype they
may be drawn worker on third one else me
queen is a female that has ability to
lay else so it's a four-time feeling and
it's too and in nature worker is also a
female but it sister I'll feeling
it's also to win a major by braun is a
meal which is an enemy so drones are
produced by parthenogenesis unfertilized
egg
oh honey we always give price
just by using this method we can also
spray some formulas
on carbon we
we'll give rise to fruit but without
seat
if we apply some growth hormone on
carpal that will develop into fruits but
because fertilization is not done so
seeds are not produced there so this is
a personal genesis moon as Sparky no
carbon
car Pistons for capital and party no
means false so here the copper give rise
to room but without any seat for now the
second category of asexual reproduction
is known as micropropagation
it's artificial mode of asexual
reproduction that can be done only in
the leverage
you
pollution is done in the laboratory
condition where tissue culture is used
to form different kind of plans with the
help of some specific called as stem
cells because this one has ability to
develop whole the plant so we have to
take 2d potentials to dependency means
complete potential to develop a plant or
an eager gas our cells of plant can be
obtained by any kind of plant tissue
whether it's a leaf or a stream or root
isolated cells are called as X plans
this experiment is always done in the
sterilized condition some cells are
isolated this one is X plant later on
these this X naught is introduced in a
culture media this one is a culture
medium
we are nutritive material along with
plant growth growth hormones are capped
this exclaimed is introduced in this
culture media this process is formed as
inoculation
as soon as inoculation is over this test
tube should be cover up by a cotton club
after the inoculation allow this X plant
to grow there after some time you will
get cluster of cell this is called as
calles calles is also known as
undifferentiated cell mass
here the expense I will obtain nutrition
from the culture media and later on at
rose and divine after the division of
cells you will get a mass of self that
is undifferentiated all the work is not
elected here and have the capability to
develop hold the plant after the
formation of callous
the differentiation get started and this
differentiation we approach to embryo
like structure which is known as embryo
this emerald is a heart shaped structure
the upper part is responsible to form
from you while the lower part is
responsible to home radical and after
this again will obtain its nutrition
continuously from the nutritive media if
there is a requirement we can replace
the nutritive media continuously and lit
it on blue moon and radicals are form
now the small plant like structure get a
rise it's known as planned it's a quite
delicate structure after hardening
the structure can be introduced in the
soil to grow like a free plum hardening
is a process to make it strong in this
condition unfavorable conditions are
introduced gradually and simultaneously
it will obtain the potential to develop
in the unfavorable condition this is
called as hardening and after hardening
this plant leaf can be planted in any
area any silos this is micropropagation
that means development of complete plant
with the help of a micro or a small
segment thank you have
