Most organelles duplicate in G1 phase but mitochondria, Golgi bodies duplicate in G2 phase,Why??

Solution

Different stages of cell cycle was observed by cytologist under microscope. so this is the nature of cell to divide some organelles in G1 while remaining in G2, So we can't say it that why they are duplicating in G1 or G2. It may be possible that S phase providing raw materials for synthesising Golgi body, Mitochondria and Chloroplast. We can only assume it.
