How many pigments are responsible for the color of a plant leaf?
1. 1
2. 2
3. 3
4. 4

After performing the chromatographic separation of a plant leaf, experimentor found bright or blue green colour in the chromatogram. Then this pigment should be-
1. xanthophyll
2. carotenoid
3. chlorophyll a
4. chlorophyll b

Range of wavelength at which chlorophyll a shows the maximum absorption is:
1. 400-450 nm
2. 450-500 nm
3. 650-700nm
4. 500-600nm

Which of the following is the chief pigment associated with photosynthesis?
1. chl-a
2. chl-b
3.chl- a and xanthophylls
4.chl-a and carotenoids
