Photosynthetic pigments such as chl a, chl b, xanthophyll and carotene can be separated by which of the following techniques?

A

paper chromatography

B

Gel Electrophoresis

C

X-ray diffusion

D

ELISA test

Text Solution

Verified by Experts

The correct Answer is:
A
Paper chromatography is a technique used to separate pigments according to their relative solubility and molecular weight. A chromatographic separation of the leaf pigments shows that the color that we see in leaves is not due to a single pigment but due to four pigments-Chlorophyll (appears bright or blue green in the chromatogram). chlorophyll b(yellow green). xanthophyll (yellow) and carotenoids (yellow to yellow-orange)
