what is the yellow-orange pigment found in the chloroplast of a plant called?

Answer 1

I think Xanthophyll is yellow and Carotene is orange.

Answer 2

Orange Yellow Pigment

Answer 3

xanthophyll

Xanthophylls are the typical yellow pigments of leaves. These are oxygenated carotenoids that are synthesized within the plastids. Xanthophylls do not require light for synthesis, so that xanthophylls are present in all young leaves as well as in etiolated leaves.

Xanthophylls (originally phylloxanthins) are yellow pigments of oxycarotenoid type, from the carotenoid group. They are found in the leaves of most plants and are synthesized within the plastids. They are involved in photosynthesis along with green chlorophyll, which typically covers up the yellow except in autumn, when the chlorophyll decomposes.

In plants, xanthophylls are considered accessory pigments, along with anthocyanins, carotenes, and sometimes phycobiliproteins. Xanthophylls, along with carotenic pigments are seen when leaves turn orange in the autumn season.

Animals cannot produce xanthophylls, and thus xanthophylls found in animals (e.g. in the eye) come from their food intake. The yellow color of chicken egg yolks also comes from ingested xanthophylls.

Xanthophylls are oxidized derivatives of carotenes. They contain hydroxyl groups and are more polar; therefore, they are the pigments that will travel the least in paper chromatography.

The group of xanthophylls is composed of lutein, zeaxanthin, and α- and β-cryptoxanthin.

Answer 4

Xanthophyll is yellow, anthocyanin is red and they combine to give yellow orange colour.
