are studying chapter morphology of
flowering plants in that we are studying
topic structure of a flower we all
have seen flower
and we all know that has different parts
mainly are made female gamete the
Corolla petals
today we'll be studying how are they
form what are their functions.
Stucture of flower we all have seen a flower
which is bright in color smells very
good but doing who that flower has a lot
of parts in it and those parts are very
essential to the fourth let's start one
by one
what are those parts the first part
patterns which are colorful which
attract either human beings or animals
or butterfly for that matter towards the
fly now patterns are also termed as
Corolla. whenever Corolla is fused and
sometimes Corolla is individual for
example in rows you can see that the
Corolla or petals are just removable
whereas in certain plants you cannot
pick up a Corolla or you cannot separate
a corner so whenever there are two types
of petals all you can say Corolla one
and Polly petal is and another as gamma
buttless now when i say gamma petal is
the color would be fused in such a
manner that you cannot remove a single
pattern example is your china rose
Cassandra whereas Polly backless can be
removed the next part is the male
gametophyte or you can say and Roscher
now this male gametophyte or and Oh
shrimp consists of an thon and a
phenomena which is a stock like thing
and inside this anther there are wheels
polar means which are the male gamete
next is the female gametophyte or the
female reproductive tract now female
reproductive basically has stigma style
and overly stigma is a hollow passage
through which for Indians we get in gain
entry
style is just the passage subin's
pulling against will add hi or you can
say they will cut our and move
accordingly inside ovary there would be
female gametes so finally during
pollination male and female gamete meet
together apart from that inside a flower
or you can see just the outer surface of
the flower has some green color
structure and those are always settles
or you can say calyx now this sepals
organics basically protect the flower in
baby stage or you can separate
not going Buffalo or you can see in the
early growing phases calyx also make
sure that the flower is protect just in
the screen ages when it has not blossom
properly beside that there is a pedestal
just to hold that flower now Corolla
attracts various pollinators like
butterflies just for the pollination
process some plants along with Hein
Corolla and calyx has perianth in them
structure of a flower flower consists of
calyx or Carroll no calyx is the green
part or it is also called as sepals this
is a part that encloses the flower in
bud stretch or in the early women's face
corolla are known as patterns and they
help in pollinating or they attract
pollinators towards them
and Russia the male part now this male
gametophyte basically turns it off and
the and phenomen and our consists or
contains pollen grains the I know shoot
is the female part which is divided into
stigma style and over some glands also
have perianth reaching this is a
structure of flower as you can see this
are patterns or you can say cover this
has surface which are also called a
calyx and this is the stem region this
is the male gametophyte now the male
gametophyte will have anthem and
phenomena together their color stem or
you can say angry or male gametophyte
whereas your female gametophyte is
called as card bill pistol or the
inertia it is divided into three
different parts stigma where the pollen
grains will enter style the hollow
passage and the ovary inside which
ovules would be present or you can say
the female egg could be present students
in this part of the chapter we have
studied about the structure of a flower
and its various parts I hope you are
clear about this concept title
