pigments work pigments basically
substances that have an ability to
absorb sun's energy in the form of
photons at a particular wavelength are
called as pigments for example
chlorophyll A chlorophyll B territory
noise xanthophyll this all are
photosynthetic pigments and this
photosynthetic pigments are present
inside grana remember the structure of
chloroplast inside grana there were
certain pigments and this are those
photosynthetic pigments now among all
the photosynthetic pigments chlorophyll
a is the most important one this is blue
green in color and the most important
pigment chlorophyll it shows the
absorption of energy at maximum
wavelength or it absorbs more amount of
sunlight it absorbs in the range of glue
to one remember physics lib cure the
spectrum which absorbs light so
chlorophyll a absorbs in blue to whine
it change next now chlorophyll a is the
main energy molecule or you can send
main accessory pigment or main
chlorophyll pigment now are so
fulfilling there are certain pigments
present which are called as accessory
molecules when I say accessory it means
something which is not important I mean
which is if it is that good if it is not
that still it will have no heart and
fashion to be present excess any
molecules of photosynthesis are
chlorophyll b carotenoids and sent often
now chlorophyll b this absorbs in the
range of yellow to green color in that
video spectrum xanthophyll absorbs in
the range of yellow whereas carotenoids
absorb in the range of orange to yellow
now if this accessory pigments are not
present will it affect photosynthesis
probably no but if they are present the
photosynthesis rate is enhanced or it is
better from helping in photosynthesis
what other other function of this
accessory pigments or additional
pigments they protect the structure of
chlorophyll
Oh beautiful basically they assist
chlorophyll-a as well as they protect
the photosynthetic pigments and the
structure of chlorophyll a
pigments in void in photosynthesis
pigments are substances that have an
ability to absorb light when I say light
it means sun's energy in the form of
photons that is starts from the range of
416 nanometers photosynthesis never use
UV rich it always use visible range and
a specific wavelength which is 460 and
the photosynthetic pigments are
chlorophyll a floor will be carotenoids
and Sandt often
hopefully the most important pigment
during photosynthesis this is the most
important pigment it shows maximum
observe absorption when I say maximum
absorption it amounts the most amount of
photons or sun's energy in the range of
blue to violet in the vape you arrange
basically accessory pigments are
basically closely B carotenoids and
xanthophyll and they enable
photosynthesis to occur in other regions
of the spectrum basically they help
during that photosynthesis in some times
Nakamura Phoebe which is an accessory
pigments absorbs in yellow and green
region of the spectrum whereas
xanthophyll absorbs in the yellow region
of the spectrum carotenoids absorbed in
the orange to yellow region of the
spectrum so maximum amount absorption is
by chlorophyll a or the master penguin
apart from helping in the process of
photosynthesis this accessory pigments
also protect learnfree a from photo
oxidation students in this part of the
chapter we have started about the
various pigments of photosynthesis that
is flown through a chlorophyll b can
adrenals and zan soften and how they
help each other to carry out the process
of photosynthesis I hope you are clear
about the concept of photosynthetic
pigments thank you
