Carotene is closely allied to chlorophyll in plants and organisms that undergo photosynthesis. It serves two roles. First it absorbs some of the sunlight that is missed by the chlorophyll molecules. Secondly, because of its high number of reactive double bonds, it makes a good 'sponge' to react with, and therefore 'mop up', energetic oxygen molecules that might otherwise oxidise and degrade more important parts of the plant structure. In a typical leaf, there is a ratio of chlorophyll to carotenoid of about 1:3, and the darker the leaf the more carotenoids it contains. Normally, however, the green colour of chlorophyll is so intense it masks the more subtle Oranges and reds of the carotenoids. In Autumn however, when the chlorophyll decays, the green fades and leaves turn red and yellow.

What is the pigment in photosynthesis?
Chlorophyll A and Chlorophyll B, beta carotene, and xanthophyll.
Give an example of accessory pigment?
beta-carotene, or carotenoid pigments are important to photosynthesis anthocyanins, which are red/purple pigments, are important in stress responses.
What function is only found in plant cells?
Photosynthesis
What is the function of the leaves of a bean?
Trapping sunlight for Photosynthesis.
How do carotene and xanthophyll function differently from chlorophyll?
carotene and xanthophyll absorb blue green light while chlorophyll absorbs all other colors of light in the spectrum. Once carotene and xanthophyll have absorbed light, they transfer the light energy to chlorophyll.
What are the different pigments of photosynthesis?
Chlorophyll a & b Carotene and Xanthophyll
What are the yellow and orange pigments found in carrots?
The pigment is known as carotene, which is an orange photosynthetic pigment, which just means it is a pigment found in chloroplasts responsible for catching light energy used in photosynthesis.
What is the pigment in photosynthesis?
Chlorophyll A and Chlorophyll B, beta carotene, and xanthophyll.
What are 2 pigments that are found in chloroplast?
The major components are chlorophyll (with two varieties, A and B), where photosynthesis takes place, and, as accessory pigments, carotenoids which are linear polyenes (such as beta-carotene) that function to fill in the absorption spectra of the where chlorophylls do not absorb strongly.
What is the function for chlorplasts?
Main function is photosynthesis .
What is the function of chlorolplast?
photosynthesis
Where does photosythesis take place in a plant cell?
Photosynthesis takes place in the chloroplast of Palisade cells of Mesophyll.
What function does the chloroplast of a flower do?
That is same in all. Carryout photosynthesis. Also involve in photorespiration
What is function of chloroplasm?
The main function of chloroplasm is to conduct photosynthesis. When photosynthesis is completed, ATP is formed. ATP is a form of energy.
What is the function of chloroplasts in algae?
It has a universal function. It carry out photosynthesis
What is the leaf cells function?
its function is to absorb sunlight for photosynthesis
Is natural beta carotene better for you than artificial beta carotene?
Natural Beta-carotene is used in health care in two ways: As Pro -Vitamin A, which is due to its ability to be converted to Vitamin A as and when the body requires, and as an antioxidant, which protects against cell and tissue damage by scavenging free radicals. This dual function of Natural Beta-carotene is due to the presence of Cis and Trans Beta-carotene isomers. Synthetic Beta-Carotene has only All-trans Beta-carotene. This inherent disadvantage of synthetic Beta-carotene has led many users to use Dunaliella, which is the best source of Natural Beta-Carotene with a high Cis-Trans Beta-carotene ratio (25:75).
