Reproduction in plants (Part - 1) - Science, Class 9 Video Lecture

the process of reproduction is a wider
correct all living means to be very
clear and the purpose of reproduction is
to multiply gate or to perpetuate to the
next generation it provides the sort of
emortality by replacing the individuals
with new one directly I am coming to the
types of reproduction the process of
producing the offsprings of the same
kind may occur in two ways one is
asexual reproduction another is through
sexual reproduction first see a sexual
reference if we see the definition of
asexual reproduction it is the univer
antal mode of reproduction means you
need to have only single of what
organism to produce is of space it
occurs problem proposals among animals
and some sponges are also involved some
sealant its communicated tunicates a
lower 48 means as such where if you
anymore groups are involved in this type
of reproduction specifically it is
prevalent among plants let us see the
types of asexual reproduction normally
four categories of asexual reproduction
one is station number two is wedding
number three is fragmentation and number
four is spoliation or the spawn of it
let us see vision first it is the
simplest form of reproduction which in
which the unicellular organisms in the
divides into two or when
is also divided in two categories one is
binary fission and another is multiple
fission baigan efficient is a type of
reproduction in which nuclear division
is followed by cytoplasmic division into
two parts and each nucleus is surrounded
by some amount of cytoplasm which makes
the two daughter cells the best example
is provided with amoeba when the same
political means more than two means you
will get more than two organisms by
multiple fish means the nucleus divides
several time this is the difference
between binary multiplications and
daughter nuclei are arranged in the
periphery which are surrounded by some
amount of cytoplasm and they form the
new organism means single cell will
produce many organism for multiple
vision the best example again it's of
plasmodium which is a causative whether
them for malaria fever the second part
is known as buddy asexual reproduction
buddy is also off to bed one is
endogenous buddy another is exogenous
buddy when we see endogenous wedding
means internal wedding this means the
bird arrives inside or within the
pennant for you for example in respondus
whereas in exogenous bedding or external
burning the bird arises from the surface
of the parents word for example in Hydra
and these during the process of burning
the bird remains attached to the parent
body for some time and after some time
it gets separated and forms the new
visual it get detached from the parents
model that has gone to the third type of
asexual reproduction fragmentation or
the lead generation although it is not
always correct then we envisioned as a
reproduction possible because we will
religion machine Nativity is present in
some higher animals like and tibial but
this process is very common in lower
planned route I would like to give
example of spiral and well this is the
body in the form of a filament tell me
if it is broken from any part then each
part as the capacity to form a fresh
filament this is type of algae wear reg
meditation the common mode of
reproduction into the last part of
asexual reproduction that is spore
formation or sporulation this form
specifically in focus some of the
bacteria such as Kukai and bacillus type
but clearly the structure is formed
chords for engine unique stuff this is
for engine is structure where nucleus of
the cell divides several vanish for me
many nucleation and each niveus is
surrounded by a bit of cytoplasm and it
goes in a dormant stage for sometimes
these posts are liberated in the
atmosphere for n1 and forms a new high
grade for example in rye so for this
type of reproduction is a common mode of
different focus this is a surface wrong
circuit and this is a tiny kilometers
bye they get attached to the substratum
and this is for ending after sometime
this bus liberating the suppose in the
air and this is for give rise to you
know height which will be very soon in
price 150 sometimes implants can be seen
this vegetative propagation it is not to
asexual reproduction not to be sexual
reproduction because here the human
efforts are more the vents for example
in glasses you can grow the new organism
from Stan only knew all the result is
obtained it can be done by the carbon
cutting for example in Rose number to
marry development of adventitious turn
first of all let us see the criticism
common mode of vegetative propagation
specifically used by Gardner to develop
various ornamental and commercial it is
also used cultivation of great as well
as in sugar and layering in this process
the development of advantageous moon is
induced on a stand before it gets
detached from the original plan for
example in men who were nearing is the
type of bearing which is utilizing
specifically lead such as in prior filim
they are the leaves are you know bunny
and they gives out adventitious roots
which gives out a new bra Phillips
similarly stem from what learning
sometimes in this ear layering is also
observed it is adapted in those plants
when stem cannot look back on the ground
in this process this chain is murdered
or bounded saying is either murder or
bounded from the
from with the legs with another plan
means the name of bar is removed from
the stand there it is stored with moist
Corbin and Reverend for avicii to
provide the moisture after two weeks
learning teaches roots develop on the
injured bar and the badge allow the root
is then separated from the pennant flag
and this part is not only is community
in orange and pomegranate if you see
diagrammatic mean suppose this is lunch
from here 30 and the new bra is against
on this side so this bar is covered with
four and layer quality is also try to
prevent any type of you know information
from outside and from this side dishes
would starts coming this is not as
drafting sometimes amount of soil is
also naked specifically place care so
the process of fear lyric is also used
some wave propagating some time
opportunity drafting can be done the
process of learning together to
different parts for that's what it was
billed as one part in future it survived
out of the two plants one is rooted in
the soil and is known as stop the other
part consists of small cheap beer
whatever it is known as CEO means if
this is stopped then the upper part is
known as CEO there is a demarcation
between these tools is the travel of
again commonly used to understand the
process of driving vegetative
propagation very fun specially biofilm
where leaves are more energy production
it is a unique example in silver plan
