Answer 2

Answer:

The plants which are kept in the dark are generally yellow, or pale green because the production of the chlorophyll pigment (essential for photosynthesis) is directly proportion to the amount of light available. Thus the leaf turns pale yellow . And Xanthophylls are more stable (yellowish in color)
