students today we are said in chapter
photosynthesis in that we are studying
topic chlorophyll or chloroplast
chlorophyll is a place where the process
of photosynthesis take place the green
pigments present in chlorophyll help in
the process of photosynthesis
chlorophyll or chloropast when I see the
structure of chloroplasts, chloroplasts
is a place where a process of
photosynthesis takes place but that's
the process of photosynthesis takes
place precisely a chloroplast probably
know there is a place inside chlorophyll
where the process of photosynthesis
takes place and today we'll be studying
what is the structure of chlorophyll of
chloroplasts and where does the process
of photosynthesis actually take this if
you see the diagram of chloroplast the
first thing that it has is outer
membrane outer membrane is nothing but
the covering then there is an inner
membrane both the membrane the outcome
as well as the inner membrane forms a
protective layer of covering for
chloroplasts inside chloroplast there
are stack of substances or stack light
thing when it is stacked like things
imagine if you're holding one rupees
coin in a bundle that is called a stack
of things
now this stack of organelles are nothing
but color-coded when you remove one
point of one rupees in your hand from
that kind of a bundle and you take that
one coin this coin would be called as
gram so when I place number of granules
together it is called as Tala point and
from one color point if I remove one
coin that is called as grana - Kailah
coils are connected by laminate organs a
bridge for various transporters in some
teleports there is something called as
photosynthetic pigments and this
photosynthetic pigments are beautifully
a chlorophyll b carotenoid xanthophyll
and now this photosynthetic pigments are
the place where actual photosynthesis
takes place so if we are saying
photosynthesis takes place in
chloroplast
it's partially to photosynthesis
actually takes place inside palak oil
which is present inside karana
and inside grana there are
photosynthetic pigments that is
chlorophyll a bee captain
or xanthophyll and this is a place where
photosynthesis actually take place now
this is the structure bed photosynthesis
takes place apart from that what else
chlorophyll have will have it's a cell
so it will have genetic material that's
DNA now imagine a cell we all have
started in lower classes if there is a
cell there is something called a
cytoplasm cytoplasm is a liquid that
holds the cell organelles in chlorophyll
plus there is a thing called a stromal
lambeth stroma lamellae is nothing but a
liquid that holds all the organelles of
true class apart from that there will be
ribosomes to carry one all kimmel to
another uncle we all know the function
of ribosome is can all protein formation
along with that there will be other
organelles like ER Golgi apparatus but
in small proportions the structure of
chloroplasts consists of outer membrane
inner membrane now put this membrane
half of protection of chloroplast inside
chloroplast you can see a stack of
things when I stay stack it means a
bundle ok now this button is something
like a five-piece coins placed in an
order this type of thing is called as an
opcode and from thylakoid if you remove
one coin or one fi'ty coin that will
form as grana inside grana there are
photosynthetic pigments which are
chlorophyll a B carotenoids and
xanthophylls and this photosynthetic
pigments help in the process of
photosynthesis so if I say
photosynthesis takes place in
photosynthetic pigments that would be a
correct sentence
along with that chlorophyll has DNA in
its the genetic material obviously so
melimeli the liquid that holds down
chlorophyll material now we have started
the diagram of chlorophyll but we
all that photosynthesis that is removal
photosynthesis equation that is carbon
dioxide plus h2 in the presence of
sunlight and chlorophyll and the
formation of glucose and it's by-product
oxygen and water this equation works
during day at night there is some
another equation so this chlorophyll is
it going to help photosynthesis
even during night you are think so this
will be studying in the ahead part of
the chapter students in this part of the
chapter we have studied detailed
structure of chlorophyll or chloroplast
I hope you are not clear about the
various aspects of chlorophyll
the structure of chloroplast consists of
a double membrane or a membrane-bound
organelle the outer membrane and inner
movement for its protection it consists
of stroma the liquid which has
resemblance to cytoplasm this is a
fluid-filled matrix whereas a matrix it
is nothing but a mesh like substances
how polysaccharides are a mesh of
networks through which molecules can
just pass through and this shoma is
basically semi permeable or permeable to
certain molecules when I say permeable
it means it allows completely certain
molecules when I say semi permeate means
it's partially allows certain molecules
now this fluid film matrix consists of
DNA that is deoxyribose nucleic acid
ribosomes that carrier molecules are
molecules which help in the synthesis of
proteins along with that it has sent you
Venice's sentiments during cell division
we all remember that there are two
centers which are located on either side
of a set and this centrioles basically
pulls apart the sister chromatids with
the help of spindle fiber basically
centrioles help turn cell division along
with that chloroplasts or chlorophyll
has talakad a stack of particular
substances or you can say stack of grana
gran-gran is basically a stack of tallow
goats from the bunch of thylakoids when
you remove a particular sub segment that
is called as crema and grana is a place
where photosynthetic pigments that is
chlorophyll a B carotenoids various
kinds of Captain oats and xanthophyll a
present grana is a place where the
process of photosynthesis takes place
and the last one stroma laminin
basically it is a tube that helps in
connection of two different substances
which could be karana thylakoid so on
and so forth
students this is a structure of
chloroplast thank you
