photosystems
Carotenoids aren’t broken down in strong sunlight, photosynthesis continues
Other pigments may act as sunscreen by absorbing blue-green & ultraviolet light - Chlorophyll A may be damaged by strong light intensities
-
-
photosynthetic pigments
The initial requirement in photosynthesis is the trapping of sunlight energy by photosynthetic pigments - 2 categories of light absorbing pigments are found in chloroplasts:
-
Accessory pigments
-
- Carotenoids (yellow -reflect yellow &orange light & absorb blue light)
-
Accessory pigments are light absorbing compounds, that work in conjunction with chlorophyll A
They absorb wavelengths that are not well absorbed by Chlorophyll

Chloroplasts
-
adaptations
-
- selectively permeable membrane
-
-
- primary & secondary pigments
-
-
- thylakoids & granum tightly packed
