Solution

Green plant kept in green light is like a plant kept in dark because plant will be not able to photosynthesise in both cases. Chlorophyll look green because it absorb light from all spectrums other then green, it reflect the green light which means it need other spectrums of light to photosynthesise. Hence, plant will be not able to photosynthesise in both green light and dark (in absence of light).
