Question

leaves of a plant kept in a dark room turned pale and yellow. if it is kept in the sun will it grow? give reason

plz help me ​

Answer 1

Answer:

Answers. 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 proportional to the amount of light available. ... Thus the leaf turns pale yellow. AND Xanthophylls are more stable (yellowish in color).

Answer 2

Answer:

The reason is that the chlorophyll pigment will be rich and increase only when it is shown towards the sun light but while placing it in dark the chlorophyll of the plant starts decreasing and the pigment will slowly begin to eradicate
