Relation between Venation and Root Types Video Lecture | Science Olympiad Class 6

hello friends this video on getting to
more plants by coating is brought to you
by example.com no more fear from example
now the question is how do we know which
plant has which type of roots so now if
I do boots are present below the ground
so how do we know by looking at the
plant that what kind of root is present
so here we are going to talk about the
relation between you nation and root X
so what is the nation the arrangement of
veins on the leaf so there is a
relationship between how veins are
arranged on the leaf with the type of
roots that is present for that time so
we will try to understand that relation
so we learned that there are two types
of relations reticulate venation and
parallel relation so when it comes to
fatty elimination it is something like
this so let's say this is the leaf so
pair elimination would mean that the
veins will run parallel to each other
something like this you see the veins
are parallel to each other so that's
parallel venation so when you look at
the leaves of that plant so you do not
need to uproot that plant to see what
kind of root is present there you just
need to observe the leaves of that plant
now if you see that they have fat will
be Nations that means the root type
would be fibrous so if the venetian is
parallel that means the root type is
fibrous and what if the relation is
ridiculous in that case it is just the
reverse so in this case let's look at
let us look at these examples of plants
where we have been in parallel venation
and therefore fibrous roots so think of
grass so have you ever observed the
leaves of grass so if you observe them
closely you will see that they have
parallel venation and if you want to
cross verify just observe their rooms
you will see that they also have fibrous
roots so in a similar way when you look
at other plants like wheat or millions
here you see a main splash when you look
at there
means they have parallel venation when
you look at their roots they have
fibrous roots so there is a connection
you can remember it this way bf that is
bad elimination fibrous russo PF is
something which is easy to remember and
if the v nation is ready too late for
example in a rose plant so the v nation
is ridiculous so what happens in
ridiculous venetian you have one midrib
or the bane rain and from the main thing
you have vein hits arising something
like this so this is how you have it in
case of a reticule eat venetian so in
reticulate venation so this is linked to
the tap root system same kappa root
system also you have one main root and
then from the main route you have
branches arising so that's stack so if
the venation is reticule 8 then the root
system is tap use so examples would be
carrot rose these are examples of the
identical elimination with tap root
system so RT that is ridiculous venetian
would have that root system BF that as
bad well the nation would have fibrous
roots so this is how you can remember it
and this is how very easily you can
determine that which plant has which
type of you thank you please visit
