The wavelengths of light most useful in photosynthesis are:
1. | green and orange | 2. | red and blue |
3. | infrared and yellow | 4. | red and green |
I: | include Carotenoids and Xanthophylls but not Chlorophyll b. |
II: | enable a wider range of wavelength of incoming light to be utilised for photosynthesis. |
III: | protect Chlorophyll a from photo-oxidation. |
