							HiOne function of carotenoids is to  absorb light in wavelength that chlorophyll is inefficient to absorbsing blue-green to green wavelength. Along the horizontal line is the range of wavelength that correspond ti visible light and which is nearly the same as that used by plants for photosynthesis. I hope you understood.

Photosynthetic pigments convert light into biochemical energy. The most efficient photosynthetic pigment on Earth is chlorophyll, which reflects green light. But chlorophyll is not the only photosynthetic pigment, and there are at least six different types of chlorophyll, each a different shade of green. 

The absorbance spectrum of chlorophyll closely matches the solar spectrum, filtered through a N2/O2 atmosphere. This close match is what makes chlorophyll the most efficient photosynthetic pigment on Earth. However, on a planet orbitting another star, the stellar spectrum will be different. On that planet, other photosynthetic pigments maybe more efficient than chlorophyll. So the leaves of healthy plants on an extrasolar planet might not be green. They could be orange, yellow, red, brown, blue or purple, depending on the stellar spectrum, the planets atmospheric constituents and the length of a day. The following is a short list of known photosynthetic and light-harvesting pigments. 
Pigment Colour
Allophycocyanin purple
Apocarotenal orange/red
Astaxanthin red
Bacteriochlorophyll a purple
Bacteriochlorophyll b purple
Bacteriochlorophyll c green
Bacteriochlorophyll d green
Bacteriochlorophyll e green
Bacteriochlorophyll g green
Canthaxanthin pink/red
a-Carotene orange
b-Carotene orange
g-Carotene orange
Chlorophyll a yellow-green
Chlorophyll b blue-green
Chlorophyll c1 green
Chlorophyll c2 green
Chlorophyll d green
Chlorophyll e green
Dinoxanothin yellow
Flavoxanthin yellow
Fucoxanthin yellow
Lutein yellow
Lycopene red
Peridinin yellow
Phaeophytin grey
Phycocyanin blue
Phycoerythrin red/brown
Xanthophyll yellow-orange
Zeaxanthin yellow

							It is due to carotenoid they help in fruit dispersal as well as pollination.. but if they are in chloroplast they increase efficiency of photosynthesis
