5.6 photosynthetic pigments Flashcards
1
Q
what are the different types of pigment in chlorophyll?
A
- chlorophyll a (blue-green)
-chlorophyll b (yellow-green) - carotenoids (orange carotene and yellow xanthophyll)
- phaeophytin
2
Q
what is the advantage of having more than one pigment?
A
more wavelengths of light can be absorbed and therefore more energy making photosynthesis more efficient
3
Q
where do these pigments combine?
A
photosystems I and II
4
Q
what is the absorption spectra?
A
the range of different wavelengths of light that a photosynthetic pigment absorbs
5
Q
what is an action spectrum?
A
the rate of photosynthesis against the wavelength of light absorbed
