Expert Answer:

When potted plant is kept in dark for a longer duration, the green color of the leaves begins to pale because sunlight isn't available to fuel photosynthesis. The green color fades from green to pale green to yellow to white. If a light source is not provided, the plant uses up all the available food it contains and dies.
