Chlorophyll absorbs all colours of
the spectrum but it
does not absorb green.
The green is reflected and
reflection provides the
colour of plants. the green light
reaches a plant blocked and exposure
the plant to colors is
maintained would be no to
the photosynthesis . Apparent
paradox: the light isnot
important photosynthesis.

There is difference between the
colour frequency for two
main types chlorophyll, the
chlorophyll and the chlorophyll .
Chlorophyll A has absorption peak at
420 nm wavelength
() and chlorophyll B its major
absorption 450 nm wavelength
().
