Vegetative Propagation by roots - Reproduction in Plants, Science, Class 7 Video Lecture

hello friends this video on to
production in plants part six is brought
to you by exam fear calm no more fear
from exam and then the final the last
mode of a sexual reproduction that we
are going to discuss is vegetative
propagation so vegetative is something
the name itself means it is something
related to the vegetation the plants so
let's see what it is it is a mode of
asexual reproduction in trance it will
in fact it is the simplest mode of
reproduction in plants so in this type
of reproduction new plants which are
formed they are exactly identical to the
parent plant in fact that is a property
of asexual reproduction right so here
plant parts detached from the parent and
they form a new plan so a specific part
of the climb is taken from the parent
and that part can give rise to a new
plan now have you ever come across a
situation where you have seen that
people take small branches of a plant
from somebody's house and plant it in
their garden and after a couple of weeks
a new plant rosa so there are specific
plants for which their specific parts
are capable of giving rise to a new
plant so this type of reproduction is
known as vegetative propagation now
vegetative propagation can be of two
types that is natural vegetative
propagation where this this type of
propagation happens through the real
plant parts for example root stem or
leaves so maybe you can take the root of
a particular plant and you just put it
in the soil in some other place it will
give rise to a new plant and all you can
do the similar thing with stem or leaves
of the plant now sense roots stem and
leaves these are naturally occurring
parts of the plant that is why all
beings fall out
agree of natural vegetative propagation
the other type is artificial vegetative
propagation where what happens is there
are specific methods by which we can get
lunch we can produce plants as we desire
by methods like cutting layering
grafting
so these are some of the methods in
which we make use of specific plant
parts and then we will do some
techniques we do we use some techniques
in order to get plants of desired
characters maybe you can actually have
plants which have characters for
different plants so you take some part
from one can you take at some part from
the other plant and then you mix and
match the two in order to get a plant of
desired character so all these would
come as an artificial vegetative
propagation so let us talk about
vegetative propagation by rooms so let's
see how vegetative propagation happens
with roots now there are certain plants
where roots are very fleshy and thick
and in fact they are used for storage of
food so these kind of roots can help to
give rise to an entire new plant so
let's see how that happens so in some
plants birds develop in thick fleshy
roots which later when put into soil
develop into new plants so as I said
when the roots the roots of such plants
are kind of swollen as you can see in
these plants whether it is guava or
sweet potato or Dahlia so this is how
the roots would look like you see it
it's quite thick it stores the food
materials so but develop in such rooms
no in fact you would have seen if you
would have ever come across sweet potato
you would have seen how Birds develop on
them do you see the roots itself can
develop buds and these bud bearing roots
when you put them into the soil new
plants will be formed because those
birds will actually give rise to new
class so that's how roots can help
in producing more plants so these are
swollen rules that can be used for
sewing next season so now it is not in
necessary that all plants will have
these type of roots that is why only
firms which have these type of thick
fleshy swollen tuberous roots only they
can reproduce by their by the process of
vegetative propagation by roots so as
you can see here on the picture this is
how those swollen roots of daniel look
like bristles are the swollen root of a
sweet potato looks like thank you please
