- V
- 400nm
- I
- B
- G
- least useful
- Y
- O
- R

- Photosynthetic Pigments
- CHLOROPHYLLS
- TYPES OF CHLOROPHYLL: a, b, c, d, e, bacteriochlorophyll
- a
- universal photosynthetic pigment
- more amount
- b
- absorb both low and high wavelength light and participate directly in light reaction of
photosynthesis
- CAROTENOIDS
- xanthopheles
- yellow to brown
- carotenes
- yellow to red
- absorb only low wavelength light and hand over the
absorbed energy to chlorophyll
