molecule that absorbs light and in visible region


During these reactions the photosynthetic pigments of the chloroplast
absorb light energy and give out excited electrons used to synthesise
ATP.

Carotenoids perform three major functions in plants : accessory pigments for light harvesting, prevention of photooxidative damage and pigmentation attracting insects.
The hydrocarbon carotenoids are known as carotenes, while oxygenated derivatives of these hydrocarbons are known as .


organic substance that is involved in photosynthesis.

The accessory pigments include other forms of chlorophyll a, chlorophyll b and the caratenoids.

A plant that is grown in full sun often produces leaves having a light
shade of green then the same plant grown under low light intensity
(shaded plants) in part this is attributable to different portions of
the two chlorophyll pigments, because chlorophyll b is very abundant
in shaded leaves, to improve light capturing capability of the
chloroplast.

There are different kinds present in plants that have been discovered recently.

What are Accessory Pigments?

Photosynthetic pigments are broadly categorized into three classes.
