Engineering HSC and IIT-JEE Mains and

are studying chapter morphology of
flowering plants in that we are studying
topic Incision of leaf when I say
Incision it means cut
we'll see how cut in a leaf affects a
plant.
incision in when I say the word Incision
Incision means cut in surgical thumbs
Incision could be a cut made on your
skin surface but then certain cuts made
on the surface of the leaf of the plant
we always see that there are thin legs
or veins present on the surface of the
knee and there is a midrate or against in
the central wings present in the leaves
through which various wings and way
let's come up now incision can be of
various types but the two common types
of incision that I've seen is one it is
seen in simple type of leaf which is a
mango leaf and another it could be seen
in compound type of leaf which would be
a tamarind leaf now whenever a incision
or cut is made in the leaf such that the
in size fat or the cut part does not
reaches up to the mid rim or up to the
Patil of the plant padule is that
holding part then that kind of incision
is nothing but simple leaf incision for
example a mango leaf which has simple
cut or simple incision the incision
never reaches the holding part or the
fibula of the gland
now we come to the next kind of incision
in this kind of incision one can observe
that small fragments of incision are C
and this small fragments are nothing but
leaflets we always see that inside
Tamblyn plants you have one video or one
holding part and there are large number
of leaves that oppressed now when this
video contains slash number of minutes
now this leaflets have been incised so
incision which is up to the midrib or
central rib of the plant is nothing but
compound leaf incision
incision or fee or you can say the cut
which happens in the surface of leaf
naturally when I say incision a simple
definition of incision would be cut made
on a plant surface now precisely
incision is seen basically on these
surfaces also in the ascetic plans like
zero fighting plants incision is not
seen we all know that as a plants have
thorns on their surface whenever the
leaf lamina is incised or you can say
cut
if the incision doesn't reaches up to
the mid rim or case of the central room
or to the PTO the folding part then that
time simple these are basically four
now in the case of fillings lamina when
it is incised or you can say cut into
smaller fragments which are lazy let's
all cancel smaller leaves attached on
one pit in simple language we can say if
in the case of tamriel needs we all as
Center on the one video there are large
number of Leafs
present and in that case if the cut does
not reduce to the middle or we can say
the central ring of the tip of the pto
then that kind of incision is nothing
but sealing compound leaves an example
of this could be your tamarind leaf or
in certain conditions plants students in
this part of the chapter we have studied
how incision can affect a plant on
simple language we can say how incision
helps to decide if the leaf will be
simply all the liquid will come on the I
hope you are clear about this concept
