Explanation:
Chlorophyll is found in chloroplast (green plastids). Chloroplast contains DNA. In plants, DNA or deoxyribonucleic acid is contained within the membrane-bound cell structures of the nucleus, mitochondria and chloroplasts. All plastids are not coloured. Chromoplasts and chloroplasts are coloured plastids whereas leucoplasts are colourless. Nucleus is surrounded by a double membrane - the inner nuclear membrane and the outer nuclear membrane.
