Among the following choose the correct statements with respect to action and absorption spectra of photosynthesis.
A. The absorption spectrum of Chlorophyll a superimposed-on chlorophyll b absorption spectrum.
B. Action spectrum of photosynthesis and absorption spectrum of chlorophyll a does not show one to one overlap
C. Chlorophylls absorb more red light and blue light than other spectral components of visible light.
D. Carotenoids absorb more red light than chlorophylls.
The action spectrum of photosynthesis and absorption spectrum of chlorophyll a does not show one to one overlap. Chlorophyll a absorbs more shorter wavelength of blue light and longer wavelength of red light. Chlorophyll b absorbs more longer wavelength of blue light and shorter wave length of red light. Carotenoids absorb blue light lesser than chlorophylls and almost do not absorb red light.
