Hence the white portion of the leaves turns green, filled with chlorophyll pigments, so that, they could be also utilized to do photosynthesis, and help the plant to synthesize the proper amount of plant food.

If the plant is kept under direct sunlight, then it the harsh sunlight is going to burn the white portion, without any doubt. Direct light for a short span is OK, but for a longer period of time will definitely going to harm the plant.
